English glass maker who developed lead glass, also known as flint glass. For several centuries, Venice had dominated the glass industry; in 1674, however, Ravenscroft discovered that by adding lead, he could create a glass that was not only more durable, but more brilliant and aesthetically pleasing than Venetian glass.
