No one knows exactly when or where glass was first made. Glass appears to have been produced as far back as the second millennium BC in Mesopotamia. Glass was a lot less common back then than it is today.

The art of glass making eventually reached Egypt. The Egyptians used a method called core-forming. A shaped core was made of clay and dung, then molten glass was wrapped around it and shaped by rolling it on a smooth surface.

It was very much later, around the end of the 1st century BC, that a new method, glass blowing would revolutionise glass production. This art was probably discovered along the Eastern Mediterranean coast, probably in Syria. By blowing through a hollow tube, the experienced glassblower can quickly produce intricate and symmetrical shapes out of the "gather" of molten glass at the end of his tube (rod). Alternatively, he can blow the molten glass into a mould.

The glassblowing innovation, along with the backing of the powerful Roman Empire, made glass products more accessible to the common people. As the size of the Roman Empire increased, the art of glass making spread to many countries.

A flourishing glass industry did not develop in Europe until the end of the 13th Century, when Venice became a major glass making center. They may have picked up their glass making techniques through their contacts with the near East countries during the Crusades. The Venetian provided the link between the ancient & modern glass making arts. Venetian glass was noted for its brilliance & for its light, imaginative forms.

So by the 15th Century, Venice had become the major producer of glassware in Europe. So highly esteemed were the Venetian glass makers, that they were forbidden to leave the Island of Murano, lest their precious trade secrets be imparted to others.

However, it was to be another 2 centuries later that in 1676, an Englishman named George Ravenscroft; searching for a way to improve the luster and clarity of his glassware found that by adding lead oxide to his molten mixture he could not only improve the clarity (crystal clear) of the glass but dramatically increase the weight, the index of refraction and the ability to cut the material without fracturing. This new glass became known as lead crystal and very quickly became the perfect medium for glass cutters and engravers. Over the past 300 years, their skills, proudly passed from generation to generation, have given lead crystal it's world famous reputation.
