Glass What

Anyone who hears the word “glass” might think of the glass in a window glass or a glass to drink from. Well, there are lots of other types of glass. London Glaziers can supply and fit bespoke styles of glass. Glass is a name that is given to any amorphous (non-crystalline) solid that displays a glassy transition close to its melting point. This is the same as the glass transition temperature, which is a temperature at which an amorphous solid becomes soft close to its melting point or a liquid is brittle close to its freezing point. The glass we know is made by mixing of sand and a few other minerals which are melted together at really high temperatures. This process forms something that is ideal for a wide range of uses from packaging and construction to the fibre optic industry. London Glazing are experts in glass. Today, we have totally mastered the glass-making process and make many different types of glass in an infinite array of colours and a massive range of products. Glass, chemically, is actually more like a liquid, but at room temperature it looks and feels like a solid. At very high temperatures, glass gradually becomes softer and more like a liquid. It is this latter property, which allows glass to be poured, blown, pressed and moulded into such a variety of shapes. The production process for glass is to melt silica sand, soda ash and limestone at around 1700°C. If other materials are added it creates different colours and properties. Even when glass is still molten, it can be moulded to form packaging, car windscreens, glazing or numerous other products. Glass can be made to fulfil almost any imaginable need. There are many different types of glass with different chemical and physical properties and each can be made by a suitable adjustment to chemical compositions. It has many specialised applications in chemistry, pharmacy, the electrical and electronics industries, optics, the construction and lighting industries, glass, or the comparatively new family of materials known as glass ceramics.
