Dark red transparent refractory glass

摘要

Glass ceramic and the process for producing a dark red glass ceramic comprising the production of basic glass by melting at about 1620 DEG C a mixture of approximate percentages of sand 53.30%, hydrated alumina 27.15%, zirconium silicate 1.90%, titanium oxide 2.02%, lithium carbonate 7.49%, sodium carbonate 0.87%, potash 0.62%, dolomite 0.39%, barium carbonate 1.04%, barium nitrate 2.16%, zinc oxide 1.09%, manganese dioxide 0.56%, ferric oxide 0.21%, cobalt oxide 0.36%, nickel oxide 0.05% and antimony oxide 0.73%. After cooling to about 1480 DEG C, the glass is formed into articles, and the articles further cooled to at least 700 DEG C. The articles are then heat treated to 800 DEG C at about
