Process for the thermal tempering of glass

TLDR
In this paper, a process for the thermal tempering of glass is described, where the hot glass is immersed in a vessel in which there are two mutually immiscible liquids, and a glass is precooled for a specific time in the lower density and then is brought into the higher density.
Abstract
A process for the thermal tempering of glass wherein the hot glass is immersed in a vessel in which there are two mutually immiscible liquids. The liquid of lower density is above the liquid of higher density. The glass is precooled for a specific time in the liquid of lower density and then is brought into the liquid of higher density.

Method of liquid quenching of glass sheets

TL;DR: In this paper, an improved method for coping with the effects of the quenching effect was proposed, where the body of the glass is cooled between the final edge and the edge of the edge at a higher rate than the rate at which the edge is reached.

Method of liquid quenching of glass

H Gorman
TL;DR: In this article, an improved method for tempering glass is described which involves contacting a first portion of heated glass with a first liquid medium having a first heat transfer characteristic of sufficiently low magnitude to minimize the danger of chill cracking, then with a second liquid medium with a different heat transfer characteristics while the first liquid Medium contacts a second portion of the glass and finally contacting both glass portions with the second liquid Medium.
