Although glass dates back to 3000 BC, it is the Renaissance period, and specifically the Venetian glass makers in Murano, who raised the level of craftsmanship to an art form never seen before. The Venetians mastered the making of a clear glass known as “cristallo”, but it was George Ravenscroft, an English manufacturer, who is credited with inventing Full Lead Crystal in 1675 – a mixture of silica, potash and lead oxide. Today, the quality of optical crystal and glass has advanced to the point where it is used in telescope lenses and large scientific prisms. In fact, it is responsible for many of our technological advances in the world.  It is this very same material that Raynes crystal awards are made from, providing unparalleled quality, exceptional clarity and prismatic colors.
