摘要

Alkalis are an essential ingredient in most glasses. St Helens developed into one of the major centres of glassmakitig in England and in its heyday produced flat glass, bottles, table-ware, insulation and TV screens, using various alkalis to help give the specific properties of the glass produced. At the first meeting of the Society of Glass Technology's North West Section David Bain looked at the changes in the alkali industry in St Helens from the early days to the present. The meeting was jointly held with the Contemporary Glass Association at the World of Glass in St Helens. Glass is everywhere, and there are numerous different types from pure silica glass to ones which do not even contain silica. Each has a different chemical composition and contains a number of different raw materials, but we will concentrate on the 'common' soda-lime-silica glasses and the alkalis that have been used in them.
