Fostoria used to be home to many glass factories. There were a pair of reasons for this. One, gas was fairly abundant near Fostoria, so it was cheap to produce the heat necessary. Two, Fostoria was on several train lines, so it was cheap to ship out finished goods and receive raw materials.
I will have to say that the stop here was pretty cool. The person running it was very friendly and he gave me a pretty good history behind both the town and the glassware. If you are in Fostoria, I would highly recommend a stop here.
