According to American ASTM C162-89, crystal glass is defined as a high-transparency, colorless glass commonly used in the manufacture of art or tableware. According to this definition, Cristallo, Bohemian potassium-calcium crystal and Crystalex and lead crystals should be included. But few people now regard Venice's crystallo as crystal glass, which has basically become a historical term.
The European Community (EEC) published guidelines in 1972 in the form of document 312/1972, which states that lead crystal glass is divided into:
(1) Full lead crystal (Full lead crystal) containing PbO ≥ 30%, density d ≥ 3.0g / cm3, refractive index nD ≥ 1.545;
(2) Lead crystal? Contains PbO ≥ 24%;
(3) The crystal glass does not clearly define the PbO content, but points out that the German market has a glass containing PbO18% and d≥2.7, which can be called PRESSB LEL KRISTALL or BLEIKRISTALL GEPRESST.
Although the EEC 312/1972 document has been published for more than 30 years, it is still being implemented. This document clarifies the area of lead crystal and crystal glass, and the lead crystal and lead crystal do not add glass. Some countries in Europe have modified and supplemented this document.
European nine national standards
BHSL 326 is similar to the EEC 312/1972 guidance document. Divided into:
(1) high lead crystal PbO ≥ 30%, refractive index nD ≥ 1.56;
(2) Lead crystal PbO ≥ 24%, refractive index nD ≥ 1.545.
