Though uncommon nowadays, owing to the fact that we’ve discovered that the chemical is poisonous, lead glass was once a common material used in the construction of many things from liquid vessels to windows throughout the ages. Empire to empire, lead glass was used in various forms for its decorative properties.
The inclusion of lead oxide in the manufacturing of glass has a tripartite effect on its production.
- First of all it raises the refractive index (RI), meaning that the resultant product basically produces a sparkling effect, as seen with Diamonds, which have a very high RI. Through exploiting crystal cutting techniques, manufacturers can create some stunning effects.
- Secondly, it lowers the working temperature meaning that its production requires less time and energy, with its working temperature only around 800°C, compared to some glasses which have a working temp of over 900°C.
- Thirdly it lowers the glass’s viscosity meaning that it’s easier to mould, allowing it to be used easily for enamelling.
Now this all sounds very scientific, and I suppose it is, but the interesting fact is that lead oxide was first used in the production of glass way in Mesopotamia. A small fragment of the glass, dyed blue, was found in the region of Nippur (an area now in modern day Iraq), which has been dated to 1400BC. There is also mention of a recipe for a lead glaze, which itself dates back to the Babylonian era or around 1700BC. However, before we get too excited about our genius ancestors, there is debate as to whether they were consciously using lead as a primary fluxing agent.
Much later we see that iron oxide is used in glass production in Han era China. Slow on the uptake, it is believed that the Chinese were taught of the uses of iron oxide as colouring agent by Middle Eastern glassworkers travelling along the Silk Road. As time went by, glass was manufactured more and more as industry developed. Across Europe it eventually came to be known as vitri Ijudaici or ‘Jewish Glass’ during the Roman period, due to the writings of Heraclius and owing to the fact that it was mostly made by Jewish workers.
Then latterly, in Medieval Europe, we see lead glass being employed extensively as the base for many coloured glasses such as stained glass windows amongst others, where the colouring of the glass was as an imitation of precious stones. It was no longer just a Jewish industry and, although there was still a rich Jewish heritage to the process, its manufacture was relocated to Venice, from which it gained high esteem throughout Europe.
Eventually a young English business man called George Ravencroft business man brought glass manufacture to the industrial scale in the 1600’s. It flourished in England until a harsh taxation was put upon the selling weight of glass, restricting profits and lining the pockets of the British government. This then lead to lead glass manufacturers creating far smaller, more intricate products, often with hollow stems – products we know nowadays as Excise Glasses. These techniques were developed throughout the 20th century and into the 21st when Fredrick C. Carder and Thomas G. Hawkes of Corning began manufacturing Steuben Glass. To this day, but to a lesser degree, lead glass is still used in decorative and industrial applications.

Townhouses were historically known to be home to wealthy people living in cities. Most Townhouses were designed and built a few centuries ago and are now becoming very popular with designers and architects who look to jig them up with a redesign, turning them into a more contemporary property.
A prime example of this is a refurbishment of a London townhouse, which was bought by an interior designer and a CEO of a media company. The five story townhouse hadn’t been updated since the early 80s, but it was apparent this was going to change when the two creative individuals moved in in 2011. In 2012 the pair requested the help of Giles Pike Architects to refurbish each floor of the townhouse. One of the steps they took to bring this property into this century was to add a double-height glass extension at the back end of the property. This breath-taking inclusion adds a real touch of class to the house, and features a stunning steel balcony with a fantastic garden view. The sheer size of this extension not only has a real wow-factor, but it also allows for a great deal of natural light to enter the property, which many town houses suffer from due to their narrowness.

Unfortunately we don’t live in a world in which we can leave our doors unlocked and our houses protected. Whilst we don’t want to scaremonger, as the threat of a break in is relatively low, it is always a weight off of your shoulders knowing that you house is as secure as it can be.
One way of ensuring this is by using security glass in your window frames. Found throughout many service industries such as jewellers and banks, this glass is smash resistant and often bulletproof. Whilst this may not be particularly pertinent for your household security, it is worth understanding the properties of the glass and what it can offer.
Often applied in areas where the glass is required to undergo a fair bit of stress, and where shattered glass might cause injury, toughened glass is tempered in such a way that it causes the glass to crumble into chunks as opposed to sharp shards. Found in shower doors, architectural doors and tables, this glass’ outer surface is compressed during its creation, whereas the inner surfaces are filled with tension. However due to the tendency of this material to shatter upon impact, it’s not generally considered the securest of glassed. However, toughened glass is also used in the manufacturing of…
Practically impenetrable, this type of glass is manufactured by combining two or more types of glass, with at least one hard and one soft. Typically this involves using alternating layers of a polycarbonate thermoplastic and laminated glass, with the polycarbonate plastic retaining a refractive index similar to that of the glass. As per the example above, toughened glass is generally employed in the design, as its tempered qualities allow it to withstand greater forces of impact.
Where a single, unprotected pane of toughened glass it likely to shatter, those layered with plastic will retain their shape when confronted by small projectiles. The glass itself flattens the bullet upon impact, whilst the plastic absorbs the rest of the force, thereby preventing penetration. The thicker the glass, the more reliably it will stop a bullet from penetrating, and as such bulletproof glass can often by up to 3 inches thick.
Whilst most homes won’t require bulletproof glass, there are other levels of security offered by treated glasses which have a thicker than normal vinyl interlayer between the panes.
As standard these types of glass typically provide a minimum of twice the amount of resistance of normal glass. So where a standard laminated glass may shatter after five blows with a hammer, security glass would take at least ten blows, by which point the intruder ought to be suitably intimidated. With developments in technology and the production of these units, this type of window security is becoming more and more available, affording the average citizen better protection.

Thermal Low-E glass (short for low-emissivity), is a type of special energy efficient glass which is designed to prevent heat loss through windows. A coating on the glass creates an invisible layer which reduces the amount of heat transferred out of the window, as well as by reflecting the heat back into the room.
These panes can contribute dramatically towards savings on the heating bill, as we already discussed, and could offer the average homeowner savings of around £170 on their annual costs of heating.
Typically, most old glazing units will not contain this glass, and are as such leaking money, not to mention their contribution to your carbon footprint. The installation of Low-E glass can go a long way towards bringing down the amount of carbon you use in a year, in some cases causing a reduction of over 600kg.
So how does Low-E Glass Work?
First we need to understand what thermal emissivity (TE) is. Consider a spectrum; on one end we have a blackbody which has a TE of 1, and on the other a perfect reflector with a TE of 0. Everything on this planet will fall into this spectrum, dependent upon the amount of heat it either reflects, absorbs or emits. Take a brick, for instance, whose TE is 0.9. We consider that it absorbs and emits about 90% of the heat that it comes into contact with, whereas it reflects only 10%. We then consider the brick to have a thermal reflectance (TR) of 0.1 – as the combined value of the TE and TR must combine to make 1.
So from this we can see that a brick would make a terrible window, not only because you can’t see through it, but because it will mean that most of your heating will be lost. Surprisingly enough, the average uncoated window has a TE of 0.91, even more than a brick, which translates to a 91% loss of heat that reaches the window.
Low-E glazing combats the naturally high TE of glass by utilising one of two methods.
- Pyrolytic CVD
Fluorinated tin oxide is deposited on the glass during the float glass stage of manufacture, and whilst the product is at a high temperature. This is also known as online or hard coating.
- Magnetron Sputtering
This process involves the depositing of thin layers of silver and metal oxides such as tin and zinc within the glass, by way of a very large vacuum. Also known as offline, soft or vacuum coating.
Whilst the actual creation process is incredibly complex, the science behind it is fairly simple. The inclusion of these oxides within the glass panes reduces the size of the wavelength allowed to travel through the glass. Infrared energy, which is the main transmission of thermal energy, is kept on its side of the glass, and so the room remains warm, whilst the smaller wavelength of visible light is able to pass through without any problems.

Many people will know of stained glass and the majestic windows that have been created with it throughout the ages. From the hallowed churches displaying the testaments in full coloured majesty, to the advent of modern stained glass and its application as an art form, it always adds another dimension to what otherwise would be just another window. Perhaps not suitable for every frame in your house, these panes can add an artistic flair to conservatories, doors, bathrooms and more.
What most people don’t know is that this is just one type of decorative glazing available to them, so we thought we’d give you a handy little breakdown of the types of decorative glass that exist.
A glass that has either been sandblasted or had caustic chemicals applied to it in order to create a pattern, you often see etched glass in saloon bars from the 1920s with their frosted caricatures of patrons. Recently this technique has been used with most abstract ‘sensibilities’ in mind, where artists create free flowing designs that ease out of the glass. You’ll often find this type of window in bathrooms and other areas where privacy is a requirement.
Though not as common nowadays due to the fact that we’ve found out lead is toxic, leaded glass has many decorative traits that can work beautifully in a modern home. With the inclusion of the metal in the potassium silicate glass, the refractive index is considerably heightened, meaning that the finished product will noticeably sparkle. Stained glass can also be leaded, with the addition of lead often used to change the colour of the glass. Nowadays this type of glass is often made by adding chemicals such as titanium dioxide and zirconium dioxide, though it is still often regarded as leaded.
Bevelled glass is traditionally made with thick panes which have been had their borders, or decorative elements cut at an angle. Cut like this, the glass produces a prism effect when sunlight streams through it, creating a rainbowed spectrum as well as highlighting the glass work. This type of decorative glazing looks fantastic in doors and cabinets, offering a high end, polished finish to the piece.
Created by incorporating glasses which have been fired at different temperatures, fused glass combines them together in order to add different shapes and textures to the finished glazing. With the three different styles creating really quite varying effects, this type of glass can create a really stunning and artistic finish quite unlike any other decorative glazing. Employed extensively by artists, if you want something truly individual for your home, we’d recommend you use fused!

As anyone living close to central London, a main road or an airport will tell you, noise pollution is a serious issue. It's been proven to cause hypertension and the sleep prevention it causes can spill out into your life as levels in concentration begin to dip. That aside it can be particularly annoying when you're trying to watch a film, or read a book as the honks of traffic and grumbling engines permeate the otherwise peaceful calm of your home.
Whilst it's one option to move to the woods, miles from any form of noise or society, the less drastic choice is to install acoustic glass, which will keep the noise outside and peace and quiet in.
At acceptable levels, outside noise often reaches around 35 decibels. Traffic can cause a dramatic increase in noise levels and reach around 70 dBs; Living under a flight path can mean excesses of 91 dBs, whilst near landing aircraft noise pollution can spike to well over 100.
In some cases the installation of acoustic glass can cut noise disturbance in half, meaning that incessant drawl of cars needn't echo through your house any more.
How does acoustic glass work?
Noise is a pressure wave that passes through the air. What acoustic glass does is effectively dampen the strength of this wave, preventing it passing into or our of your house. It does this by employing a separate layer between the two panes.
Utilising Polyvinyl Butyral (PVB), the two sheets of glazing are laminated together, giving them the appearance of being a single pane. This layer of PVB acts as an acoustic membrane, absorbing sound energy and preventing the vibrations of the sound wave actually passing through the glass. As a result, most of the sound is reflected back away from the glass, either back into your property, or kept out on the street.
The noise reduction experienced will further depend upon the pitch of the sound, though under normal circumstances the reduction can be dramatic in regards to traffic, aircraft and rail noise.
However, it's not just the acoustic glass that is required for effective noise reduction. Many ill fitting window frames contribute significantly to intrusive noise disturbance. In fact a gap around the window frame equal to merely 1% of the actual frame size can allow a not insignificant 10 dBs into your property.
Double glazing is everywhere, and unless you have been living under a rock you will know all about its energy efficiency and capacity to reduce noise pollution compared to older single pane windows. What you may not be aware of is the fact that triple glazing is now an affordable option when building or renovating your home, and can offer a marked improvement upon standard and even advanced double glazing units.
Similar to double glazed windows, triple is formed of three separate panes of glass, more often than not of low-e standard, separated by an inert gas like argon and heat insulated spacer bars. The difference lies in the insulation properties of double vs. triple glazing.
In modern double glazing units the energy efficiency (u-value) averages out around 1.6, whereas in triple glazed windows you can expect a u-value of about 0.8, meaning that triple glazing is doubly efficient. In places like Scadinavia where every step towards a thermally insulated property is a necessary one, triple glazing has now become the standard due to its ability to keep heat inside the home.
However, the benefits don't stop there, as glazing also offers a considerable improvement in noise reduction. A property, measured in decibels, which denotes the reduction of noise between partitions, the Sound Reduction Index (Rw) of a double glazed unit is often around 32dB, whereas with a triple glazed unit you can expect an Rw of 41dB. This is a 30% increase and will offer markable differences in areas where noise pollution is a real problem, such as near airports and busy motorways.
So Should I Switch From Double Glazing To Triple Glazing?
The short answer is perhaps not. Whilst triple glazing will offer you a clear increase in heat insulation and noise reduction, they can be fairly expensive and, in terms of payback on energy bills, it will be a while until you see a return. That said, there are certainly tangible, if not monetary benefits to changing your windows
Triple glazing will reduce your energy consumption and thus your carbon footprint, which is something that I would recommend everyone does. Also, if noise pollution is a real concern then I would recommend replacing double glazed windows with triple, as the difference is certainly noticeable.
Another benefit seen from installing triple glazing is a reduction of cold spots in a property. Where the higher u-values of double and single glazed units creates a differential in temperatures between the windows and the wall, triple glazing goes a long way to reducing this.

It can be a terrible pain to move into a new home and find out that just around the corner is a late night bar or a road that doesn't quiet down until 4 in the morning, but you don't have to suffer in silence (or the lack thereof).
We often have clients inquiring as to what benefits they can expect from installing acoustic insulation windows in their property, and whether it is actually worth them doing.
The simple answer is that if you are experiencing a great deal of noise in your property, it is absolutely beneficial for you, though depending upon the extent of the problem the solution can vary.
What are the Solutions?
The two basic options available are:
Secondary Glazing units
These are used in properties where there may be an issue with noise insulation but it isn't a big enough problem to require a whole overhaul of the window unit.
-Mostly for small amounts of noise traffic/social environment.
Acoustic Insulation Windows
-This system is a lot more expensive and requires a complete overhaul of the windows units in your home.
-Used when houses suffer from a great deal of traffic/overhead aircraft/industrial processes.
What Difference Will I Hear?
With either solution, there will be a noticeable reduction in ambient sound getting into your property. With the installation of acoustic insulation windows, you will see the most dramatic difference of over 30 dB
Put it like this:
1dB is an unnoticeable reduction in noise levels.
5 dB represents a noticeable reduction in noise.
10 dB is double a reduction in sound disturbances.
Therefore with the installation of soundproofing glass and window frames, you will encounter only a sixth of noise that you previously would have. A truly startling reduction.
What Other Benefits Will I See?
By default, these systems will also help with heat insulation which can produce a marked decrease in your heating bill all year round.
The most reported difference, however, is that many people find themselves feeling a lot better having been able to relax at home and getting a night of undisturbed sleep. Children and babies aren't woken up and you'll save yourself from the pains of crushing a pillow over your ears at night.
The addition of these windows will also add value to your property, plus they are available in new and updated styles that will enhance your home's aesthetic.
All in all, if the noise of your street or local environment is keeping you up at night, then acoustic insulation can provide you with very perceptible benefits.

I'm sure you've been plagued for years by cold callers offering you exclusive double glazing deals, or accosted by salesmen as you leave the supermarket with you weekly shop. It's become such an issue now, that when people think of double glazing, it's synonymous with pushy sales techniques and deals that quite frankly seem too good to be true.
Well, we want to change that perception. At Hugo Carter we pride ourselves on finding the best solution for each individual client. That's why all of our prospective customers get a free quote and evaluation, so that we can ensure we are doing our best for them.
With a great deal of packages available, it's also worth knowing what your options are before you buy. So here's a brief run-down of what you can expect from installing new double glazing systems in your home.
Heat Insulation From Double Glazing
Whether you have sash or casement windows, the benefits of installing double glazing are instantly recognisable in regards to the ambient temperature of your property. Where single glazed units will allow heat to flood out of your property, double glazing's two frame system creates a barrier which prevents such drastic loss. Translated into money saved, A-rated double glazing (the best available) can save £400 or more on your yearly bill.
That's a pretty good return when moving into a new family home, where savings can reach around £8,211 over a 20 year period in a semi detached property. This is also calculated to save 22 tonnes of Carbon dioxide over the same period of time. For a more detailed estimation of what it could save on your property try out this energy saving calculator.
Acoustic Insulation From Double Glazing
Aside from keeping you warm in the winter, double glazing's biggest bonus is the sound insulation that it provides.
We've found that many people will move into their new properties, only to find out that there's a late night club down the road, or air traffic rotating overhead. It's an unbearable nuisance for anyone, not least those with small children.
In most cases where noise pollution is a minimal disturbance, outweighed by the need to keep the heat in, our standard double glazed window units are what we'd suggest.
Though simple double glazing units can offer noticeable reductions in noise pollution when compared to their single glazed competitors, the set up of standard units generally don't offer the best the market can offer.
Instead, when noise pollution is a real nuisance, we suggest installing noise reduction windows, which offer far greater acoustic insulation. By using asymmetrically thick panes of glass, the sound waves are mitigated a great deal more than in systems where the panes of glass are of the same thickness.

With the width of single glazing, vacuum glazed windows offer the same thermal insulation as their double glazed counterparts. The question is, how?
How Does Vacuum Glazing Work?
Unlike Dyson hoovers, which frankly no-one apart from Jeremy Dyson understands, the mechanics of vacuum glazing is really rather straight forward. Instead of using air or other combinations of gas between the panes of glass, vacuum glazing instead employs a layer of nothing. With there being nothing between the glass, there is nothing to transfer the heat between the panes, and so it can’t go anywhere. Heat can’t go anywhere - room stays warm.
Of course, it’s still possible for heat to be transferred through the actual frame, though this is the same with double glazing. Rather, the use of microspacers, a low emissivity coating and specialist sealants ensure optimal efficiency.
The Differences Between Vacuum Glazing and Double Glazing
In terms of energy efficiency, there are practically no differences. Vacuum glazing provides the same level of thermal insulation at a 0.2mm gap between panes as double glazing possibly could. So there’s no trumping there.
Instead, the incredible advantage of vacuum glazing lies in its relative thickness. Where most double glazing units will come to around 24mm, and possibly more, vacuum glazed units are around a third of the size at 6.5mm. This remarkable fact means that vacuum glazing is ideal for those who are looking to update their windows from single panes in conservation areas or listed buildings.
As we all know the regulations on changing anything about your property in one of these areas can cause a massive headache, and often this smallest details, such as the exacting dimensions of your windows and their frames, cannot be altered. With a much smaller thickness, it becomes a whole lot easier to design like for like replacement window frames which can accommodate the vacuum glazing, offering four times greater thermal efficiency compared to single pane units.
Other Advantages of Vacuum Glazing
Aside from the size difference, vacuum glazing also offers improved acoustic insulation. They will increase the value of the property itself, and with the energy saving you experience, will reduce those ever increasing heating costs!

Our line of bespoke soundproof windows is one of our most popular especially with our London based clients who are often kept awake by overhead planes, traffic or nightlife. Whilst it’s great to live as close to the city as possible, the reality of noise pollution is a genuine struggle and we’re delighted we can help by installing a total solution.
However, we do get a lot of inquiries from people asking just how much of a difference soundproof windows make. The fact is that noise and sound levels are a complicated science based on a logarithmic scale which can be really quite confusing if you’re not mathematically minded. So the question is, what difference can you expect from installing soundproof windows?
Measured in decibels, sound is a pressure wave that propagates through the air. Don’t worry, this is as scientific as we’re going. The more power in the wave, the louder the sound.
The decibel scale, like the richter scale, increases as a multiple ten. If you say a sound of 10 dB has a power value of 10, a sound of 20 dB has a power value of a 100 - it follows that a noise of 30 dB has a power value of 1,000.
Still a little confused? Our noise reduction explanation below should help:
As you can see from our soundproof windows infographic, installing our total solution guarantees a whopping reduction in noise pollution of at least 1000%, often offering far greater reduction based upon the bespoke system installed for your property.
There’s not really any better way to demonstrate the effectiveness of noise reduction windows than to show them in action, so have a quick look at the video below in order to truly understand the effects of soundproof windows on a busy London street.
Staggering, isn’t it? The hum drum of inner city life becomes inaudible and a stillness permeates through the property. If you suffer from the nuisance of noise pollution we can genuinely say that there isn’t a better product around to deal with the problem.

What Are Soundproof Windows?
A revelation in noise reduction, soundproof windows are the total solution to the problem of noise pollution in London. Tackling every aspect of intrusive noise, soundproof windows utilise the following in order to make your property peaceful and serene:
laminated glass to dull sound waves
the space between panes is optimised to reduce noise
timber frames are specifically designed in order to prevent noise pollution
secure fittings ensure there are no gaps in the frames/no reverberations
With a totally scientific approach to preventing unwanted noise in your property from the very beginnings of design, their sole purpose is to ensure that there is no sound penetrating from the outside world.
How Does Secondary Glazing Work?
A solution for noise reduction, secondary glazing is a system that can be put in place in almost all properties and most window designs. Fitting into the original frame design, secondary glazing solutions effectively just place a secondary window frame unit within the property in order to create another barrier between the sounds of the world outside.
Creating another barrier helps to dampen the sound waves, especially when the thickness of the secondary glazing unit is different to that of the original units, secondary glazing basically just adds a layer of sound insulation.
Soundproof Windows Vs Secondary Glazing
In order to give you the best overview of the products, we’ve laid out the most important factors to consider and how each solution fares in regards to not only sound proofing but other factors too.
The most important factor first. Soundproof windows provide better sound reduction. Hands down. Designed from the ground up to reduce sound, and tailored to the individual property’s specific noise problem and providing a holistic solution, quite frankly there isn’t a better solution for reducing intrusive sound.
That said, secondary glazing does provide noise reduction. It will absolutely noticeably make your property quieter, just not to the same degree that soundproof windows can.
Installation Of Noise Reduction Windows
Soundproof windows are a bit messy in this regard. You will need to entirely replace your original window frames which is a fairly long process. That said, employing a proper soundproof windows company will mean that the job can be completed in only a few hours (depending upon the size of the project, of course).
On the other hand, secondary glazing units can often be put in place on your own. This will take as long as you take over it, but alternatively there are a wealth of companies which will come and install their own secondary glazing units at your property. This means you get to keep your original windows in; no mess, no crew required if you don’t want them.
Of course, installing yourself does mean that you can get things wrong and nullify their effects, and the benefits of hiring an established firm will outweigh the few pounds you will save. And so we come onto…
The Cost of Soundproof Windows Vs The Cost Of Secondary Glazing Units
No prizes for guessing what wins out here. Well, ‘wins’ is perhaps the wrong word. Secondary glazing units are far cheaper than the former, but that’s not necessarily a good thing.
If you’re on a shoestring budget and have a heinous problem with noise pollution which is keeping you awake at night, then secondary glazing will most certainly help and will most certainly reduce noise. Even more so if you decide to install the secondary panes yourself.
Soundproof windows are on the opposite end of the spectrum. They are expensive solutions, but that’s clearly not a bad thing. They are expensive because they provide the best solution possible; they are tailor made for your property. In fact, they will actually add value to your house because it means that those who you may sell it on to will not have to install the windows themselves!
Thankfully both soundproof windows and secondary glazing units will offer you a degree of thermal insulation. Hooray!
Creating an additional barrier between your inner sanctum and the world outside, secondary glazing creates another buffer between cold air, reducing heat loss through the window panes themselves.
Soundproof windows, due to their very nature; the fact that every single element of the frames are insulated from any possible gaps in their frames, offer far greater thermal insulation than secondary glazing.
In fact, soundproof windows offer double the thermal efficiency of second glazed units. Double… which means double the savings on your bill too!
Issues With Soundproof Windows
The main issue with soundproof windows is that quite often they will require planning permission due to the radical nature of the transition. In conservation areas this can be even more of a headache due to the need for like for like replacement windows, though expert manufacturers can create solutions which will pass even the strictest of local councils.
Issues With Secondary Glazing
Cleaning secondary glazing units is rather a pain. You effectively have to clean two separate window units and this can be kind of awkward depending upon the space you have.
Due to their design, secondary glazing often caused a great deal of condensation on the primary glazing unit. This is another pain to wipe down due to the fact that you have a sheet of glass in the way.
DIY units are often not sealed very well which means that they become pretty much redundant.
The Conclusion. Which Is Best?
Well, quite frankly it depends upon your circumstances. If you don’t have the budget to replace the windows in your property then secondary glazing will go some of the way to reduce noise pollution as well as improve thermal efficiency.
If you do have the budget, you simply have to install soundproof windows. They add value to your property and provide a total, lasting and holistic solution to the problem. They will reduce noise pollution far more than secondary glazing and look far more elegant. Secondary glazing encroaches into your room whereas soundproof window frames will fit snugly within the aesthetic of your property and look gorgeous.
