Manufacturing

In 1952 Alistair Pilkington invented the float glass process. This process used a horizontal method whereby glass was drawn over top of a bath filled with molten tin. This method is still the most common method of glass manufacture today.

Toughened glass is essentially made in the same way as normal, annealed glass. The only difference is that there is an extra stage at the end of the manufacturing process which adds around 3~ 5 times greater strength than the ordinary annealed glass.
