alot of businesses go with lastname "somthings" or region "somethings".
like Laza Glass Studio or Vancouver Glass Studio.
One of the local artists here does bronzes his is called High Prairie Bronze Studio, because, well we live on a prairie.
You could also do something generic like Glass Blowers. I teased my GF about that place cuz we went there on vaca and she wanted to buy the store, so I called it "Cash" Blowers.
Or, you could do something unique. Does glass blowing have any specialized tools or terminology that you could mash together to invent a word?
I was at one time a partner in a company called RescueMyPC. You might guess that we fixed computers, but it didn't say H3LR4ZR's Computer Repair. Our marketing was like an ambulance. the logo had a + sign and our slogan was "Rescue me!"
In the end, it has to be something you come up with at its a very personal decision and one you will be sticking with for years to come and maybe not the best thing to leave other people to decide for you.
In any case, if your selling to tourist types who mostly just see the shop and decide to stop in because its something to do, it probably won't matter too much what you call it, and you can always change it later by doing a DBA. Don't forget to make sure your name isn't already trademarked. You don't want to end up in this situation.
