Glass is a peculiar material – it is not a solid, it is rather a slowly flowing mass which allows the glass-maker to produce his fantastic creations. Glass products can look incredible – as if the molten glass' movement has been frozen and captured. Just one of the things that makes glass-work so fascinating.
A temperature of 1300 degrees is required to transform sand, soda and lime into glass. The glass-maker blows the glass with his "pipe", the temperature falls and the glass changes. At 1000°C, it is syrupy and at 800-900°C, it becomes tough and thick. Between 500-600°C, the glass starts to stiffen and harden and it is in this brief period when the glass is firm but flexible that the glass-maker can form his product and give the glass identity.
