摘要: For the production of a bubble-free vitreous material, and in particular bubble-free vitreous silica, bubbles-containing vitreous material is exposed in a furnace, at a temperature which reduces its viscosity to a value between 10.sup.13.5 and 10.sup.8 Pa.sec, to the omnidirectional pressure ranging from 100 to 3000 bars of a gas which is insoluble in the vitreous material for a period of not less than 10 minutes and is then cooled.
