Abstract

A sort of molding frame for manufacturing quartz glass articles, by heating under 1750 degree C-2100 degree C and under pressure of 0.001-1kgf/cm2 for forming frame of the quartz glass, featuring, in the graphite frame forming the space, having said quartz glass in opposite directions, and with a pair of graphite molds, which may be formed by reducing quartz glass molds; being the pair of graphite molds in contact with the quartz glass with pressurization for forming is of a permeability rate of 0.1cm2/sec(p:1.5kgf/cm2) and more and a compression strength of 100kgf/cm2 and more, and a short hardness of 10, with tiny ventilation pores as graphite material; and said graphite frame is made of graphite material of higher strength than that of the opposite graphite.
