If you browse the images on his site some of the large sculptures, as well as table and counter tops, list "pyrex" as a material used.

That doesn't necessarily mean he has/had a furnace. Many look like they are cast from chunks rather than hot poured.

I'm still wagering you won't find a private studio with the infrastructure to melt boro from a raw batch formula. The bong suppliers are doing it with cullet.
Temperature and time.
