Abstract

Method of manufacturing glass objects for molding and pressing a glass mass, in the form of a sleeve, characterized in that it consists of depositing a mass of glass, of slightly greater weight than that of the finished object in a bottom mold body retractable towards the bottom part and initially sealing the lower part of the body of the mold, in order to penetrate the die in the glass mass until it abuts the bottom, in order to form the central passage of the hollow body, a veil of excess glass of small thickness that then the lower part of the sample of the object formed in this way is retracted to submerge said bottom in order to submerge the die further in order to shear said glass web at its periphery, to raise the die again and to demold the finished object.
