Abstract

PURPOSE: To provide a semitransparent glass having silky gloss which consists of SiO2, Al2O3, R2O (R is an alkali metal), BaO, CaO, SO3, and a halogen as the basic component in which a part of the components is uniformly distributed as BaSO4 and CaSO4.
CONSTITUTION: A semitransparent glass having a soft silky gloss consists of 60.0W 85.0wt% of SiO2, 0.5W10.0wt% of Al2O3, 2.0W25.0wt% of R2O (R is an alkali metal), 0.3W20.0wt% of BaO, 0.3W20.0wt% of CaO, 0.1W3.0wt% of SO3, and 0.1W9.0wt% of a halogen as the basic composition, in which a part of BaO and CaO, and a part of SO3 form into microcrystalline BaSO4 and CaSO4 and uniformly distributed into the glass. This glass allows BaSO4 and CaSO4 crystals to gradually grow in the glass matrix so the degree of semitransparency is easily controlled by regulating the treating conditions such as melting temperature and treatment time.
