The ancient craftsmen who created it jealously guarded the secrets of glass making.
To this day, it still fascinates – combining strength with clarity, fragility with permanence,
it is an “everyday” material which can be transformed into stunning works of art.
To produce glass, silica (derived from sand, flint, or quartz) is melted with lime, potash and soda in a furnace,
then poured and floated on a bed of molten tin. This mass slowly solidifies over the molten tin as it undergoes a
controlled cooling process in an annealing oven. Compounds mixed with the silica can impart any characteristic
or colour required for function as well as appearance.
Controlled variations in temperature and cooling rate further affect physical properties such as hardness.
