==History==
The Romans first pulled glass into sheets for making window panes around 400 BC. However, they mostly used it to make jewellery. Around 50 BC, the glass blowing pipe was invented - this new technique was used by the skilful Romans to manufacture drinking vessels and other containers. It was not until 600 AD that real sheet glass was first produced in Germania. Before coming into general use, it was first used to decorate huge cathedral windows. The great challenge for the master glass blower Bernard Perrot of Orléans was the production of mirrors. He pressed the heated glass with a metal roller to obtain a perfectly smooth surface.
==Did You Know That?==
Friedrich Siemens first used a heated iron mould to produce pressed glass in 1874. At that time, the price of hard glass went down by about a third, opening up a large market for the manufacture and use of glass bottles in many new cities. Realizing his chance, Siemens quickly changed his production from sheet and plate to bottle glass. As many people now have higher incomes than before, they can afford the luxury of buying bottled whisky, wine and beer.
