Understanding Glass

The glass we use is a mixture of sand and other minerals that are melted together at a really high temperature to produce a material that is perfect for a massive range of uses from packaging and construction to fibre optic technology. London Glazing can advise on glazing for your home.
A form of the glass occurs naturally within the mouth of a volcano as it erupts there is a formation of something called Obsidian which is glass like but very tough yet brittle and has very sharp edges. Obsidian has in the distant past been used for cutting tools and even been experimented with as a medical tool. Glass is actually more of a liquid as it stands, yet feels solid, but will at high temperatures become softer and look like a liquid. Of course this is why glass can be poured and manipulated, molded and blown. Today man has conquered glass productio and can make many different types of glass. London Glaziers understand the process for making glass.

The Making Of Glass.
The glass we know is manufactured initially with the melting of different minerals at really high temperatures. The principle element in this process is something called Silica, (which is one of the most commonly found sands on earth) which combines with limestone and something called soda ash and they are melted at around 1700°C. During this process the manufacturer can add various different materials to change colour or the glass’s properties. Glass can be covered with a coating, treated with heat, decorated or even engraved for different uses. When the glass is in a molten state it can be formed into things like windows, screens for cars or packaging, in fact there are lots of uses for glass. It will depend on it’s ultimate use as to the rate that it is cooled and also it’s composition.
