<p>[QUOTE="George Nesmith, post: 154228, member: 177"]Manganese was used to clarify crystal ie colorless glass in place of lead. That stopped when WW1 interupted the supply from Germany. The suns UV rays would tickle the manganese and cause a pale purple or amethyst color in the crystal glass. I do not know what chemical was used to give color to your purple vase. ( In the EU crystal has lead in it. The US makers used it to refer to color not chemical composition.) I agree an attractive recent bowl.[/QUOTE]</p><p><br /></p>
