How Lead Crystal is Made

Composition

Lead crystal glass is made from a mixture of sand, potash and lead oxide. The type of lead crystal glass is determined by a British specification (BS 3828: 1964) for each type. Lead crystal glass contains a minimum lead oxide content of 24% and is produced primarily for its beauty of appearance. Full lead crystal glass contains higher amounts of lead oxide usually not less than 30%. This higher content of lead oxide enhances the beauty of the item but it is more costly to manufacture.
