Definitions for "Lead glass"
An early type of glass made with lead oxide and resulted in clear or white appearance.
Discovered by George Ravenscroft in 1673. Often (not strictly correctly) called Flint glass, it contains Lead Oxide, as opposed to Potash glass or Soda glass. It cools rapidly, making it hard to manipulate into complex shapes, but its hardness and brilliance make it well-suited to cutting and engraving
So called because it contains around 25% lead oxide and popular in most parts of the world for use in the manufacture of cold cathode tubes and in particular the electrodes.
