Vase

The recipe for making glass has changed little for several thousands of years: sand, alkali ashes, and lime from crushed stones are melted together to give a strong, yet fragile material. This molten material can then be manipulated by the glassmaker in a number of ways.This 19th century, English vase was mould blown. This is where a bubble of molten glass is blown into a mould, which determines both the shape of the piece. It is made out of white opaque glass which gets its colour from tin oxide. White opaque glass became popular with the demand in the 17th and 18th centuries for porcelain from China and later from European factories.
