Tom,
Maybe you should "start" your search on this topic at the introduction of "commercial glass".

Here are a couple of lines from that site:
1800 - Industrial revolution dawns a new era in glass manufacturing. "Synthetic" chemicals for glass making are available for the first time. Synthetic glasses with improved properties become available.
1863 - sovay process dramatically reduces cost of a main ingredient in glass, sodium oxide.
1867 - Siemens brothers, Freiderich, Karl, Hans, Werner and Wilhelm patent and develop first regenerative glass furnace in Dresden, Germany
1875 - Technical glasses are developed in Germany, Abbe, Schott, and Carl Zeiss. University of Jena, Jena, Germany becomes a major glass science and engineering center. Glass chemistry is in its infancy.

Rawson and Evans was dealing with it in the 1875 period. Sounds like you are on the quest for knowledge...so let us know what you find out. I am content to know it has been around for 130 years or longer.
