A method of manufacturing glass bodies, in which the starting material for the glass body, being an extrusion mass consisting of microdispersed SiO2 particles, a binder and a dispersing liquid, is used to form a porous green body by extrusion, which is subsequently dried, purified and sintered, the extrusion mass, which is shaped by the nozzle of an extruder, being extruded into a transfer vessel in which the extruded body is tempered towards the gelification point of the binder present in the extrusion mass, a liquid being contained in the transfer vessel, which cannot or substantially not be mixed with the dispersing liquid present in the extrusion mass, and which cannot be mixed with the binder present in the extrusion mass; and an arrangement for carrying out this method.
