The Facts Of Glass

The glass we know is a mixture of sand and other minerals which when melted together at a high temperature makes a material that is perfect for a wide range of uses from packaging, construction and fibre optical equipment. There is form of glass that naturally occurs inside the mouth of volcanoes as the searing heat of an eruption melts the sand to form something called obsidian, which is a hard black glassy stone. Early humans made spear tips from this. Modern man has conquered glass making and can make many different types of glass in infinite and varied colours and a huge product range. The largest element for glass making is sand. This melts at about 1700°C with which other minerals are added to reduce the temperature for the melting process. London Glaziers recycle glass responsibly. Commercial glass is usually colourless to allow the transmission of light, which is great for the window and other uses also. Other chemicals for colour can be added. Flat glass has a very similar construction but has more magnesium oxide in its composition. The glass we use today is 100% recyclable and can be recycled time after time without losing any of its quality or strength. Archaeologists found evidence that man made glass and was dated right back to 4,000BC. This looked like coated stone beads. It has been discovered that the egyptians in 1,500 BC made the first glass bottles in a format we would recognise even today. Whilst the glass is still molten, it can be manipulated to make packaging, car windscreens, glazing and various other products. The end use dictates, the composition of the glass and the rate at which it is allowed to cool. London Glazing supply and fit all types of glass.
Did you know that glass is inert. This is a great thing as it guarantees your food will never have a glass taste. The glass we use is actually the only packaging material that has no requirement for extra layers to protect your food from tasting as it should. If you like good food, the choice is clear as … well, glass.
