The technique of making such glass has been known for several thousand years. Now glass with the same the same attractive qualities can be made without the use of lead. Facetted crystal glass ‘stones ‘ and beads produced by Austrian, Czech and Chinese companies are widely used in jewellery. Crystal glass is also use to produce attractive drinking glasses and decanters and a wide range of decorative items.
