ABSTRACT:
A device for shaping rods, in particular, of a glassy material, by casting said material in a molten state in a mold, characterized by the fact that said mold comprises a) a cylindrical internal wall of a porous material and b) a means to inject a gas in this wall and cause it to come out of the wall on the side facing the glassy material accumulated in the mold, so as to constitute an interstitial flow of a film of gas that separates the glassy material from the inside wall of the mold.
