Manufacturing method for sparkling black glass

Abstract

A black sparkling glass comprises: Fe2O3 0.13-0.20, NiO 0.15-0.19, CoO 0.014-0.019. It is produced by: melting stably at 1560-1570deg.c, removing carbon powder and having sal mirabile content<4%, and stirring mechanically. The method can be used to eliminate black strips and bubbles.

Description

Technical field: [0001] The invention relates to a production method of crystal black glass. Background technique: [0002] Crystal black glass has the ability to control the penetration of sunlight and heat radiation, and has an elegant color and soft light, which can be effectively used in heat insulation, decoration and other fields. At present, the production of crystal black glass is based on the production process of ordinary glass. Colorants are added to the main glass components. Under the action of colorants, ordinary white glass becomes crystal black. However, in the production of crystal black glass, the purity of color Difficult to control, prone to uneven color, such as black stripes, etc., and bubbles, which are not easy to exclude. Invention content: [0003] The object of the present invention is to provide a method for making crystal black glass that can effectively prevent color impurity. [0004] In order to achieve this purpose, the technical scheme a...
