It looks like a good site for a company. If you are able to take a class there, that would be helpful for you. I haven't used a kiln for both glass and pottery. Glass requires a low temperature, and an annealing cycle as far as I know.
Take the class and try to talk to the techs there. Find out as much as you can about the needs of a kiln for glass beads...might as well include slumping glass which you may grow into.
Then do more research to see what qualities you need for both and if it is feasible to use one kiln.
Thanks for the input. I really do want to do the glass slumping more than the glass beads. More my style. I will definitely take the class and go from there.
