Crystal Ingridients. Crystal is made of silica, sodium carbonate and calcium carbonate or more commonly known as sand, soda ash, and limestone. Soda ash is added to the sand in order to lower the melting point and limestone is added to increase crystal's strength and durability.
Lead Crystal. Lead crystal is made from glass that has been treated with lead oxide and hand or machine cut to make facets. This gives the glass a higher index of refraction and creates an attractive sparkling effect that is prized throughout the world. Englishman George Ravenscroft is credited with discovering lead crystal in 1676.
