Abstract

"Glass sharpening device", including an elongated channel in which the fluid mass of the glass comes from a prefusion device and is subject to an expansion, of at least fifty percent, in all its thickness, by rapid temperature rise, characterized in that the heating of the channel is ensured by horizontal electrodes arranged in parallel, along each of the longitudinal walls of the channel, close to the hearth.
