Abstract

The subject matter described herein includes a method of manufacturing colored borosilicate glass including, preparing a raw material composition to form a homogenous powdered mixture, placing the homogenous powdered mixture in a container, heating the mixture to a temperature of 2500-3000° F., charging the container with additional homogenous powdered mixture until the container is full, melting the homogenous powdered mixture until it forms molten borosilicate glass, and refining the molten borosilicate glass between 2800-3200° F. to allow air to escape and the glass to fully homogenize.
