Creation of Lead Crystal: In the 17th Century, a process vital to the development of crystal was patented, states the Irish Culture and Customs website. The English glass maker George Ravenscroft discovered that by adding lead oxide to molten glass, he could create a rock solid, sparkling substance that was soft enough to carve. Thus lead crystal was born.
