METHOD OF OBTAINING SILICATE GLASS Russian patent published in 2014 - IPC C03C3/00 

FIELD: chemistry.

SUBSTANCE: method of obtaining silicate glass is realised due to the application of a combined charge mixture, which contains quartz sand of the fraction 0.1-0.9 or quartz grains of the fraction 0.1-0.4 in an amount of 70-100%, preliminarily moistened with a solution of metal chloride salt in an amount of 0.05-1.5 wt %, and amorphous silica in an amount of 0-30 wt % separately or in a mixture with the remaining charge components with humidity 0.1-5%. Light permeability in the visual part of spectrum constitutes 90%.

EFFECT: obtaining highly transparent glass and acceleration of the melting process.
