Process for the manufacture of vitreous pieces including gaseous particles, in a controlled manner, of the glass mixture of small particles and substance or substances that produce gas at a temperature higher than the melting temperature of the glass, forming a continuous piece or piece of this mixture, subjecting them to heating, melting them, creating gaseous particles in the vitreous mass, characterized in that the composition of the mixture, the compaction, the temperatures, times and other factors will be regulated in such a way that the expansion, caused by the creation of the particles gas, equal to the retraction caused by the melting, inferior to it, or higher than it, so that the change of the linear dimension of the piece during the heat treatment does not exceed 15% per cent.
