The space has a small chilipepper kiln for annealing off the torch as well as a few standard kilns in the back for batch annealing. Kilns do not care what glass you use, I was recently using up a ton of my small rods making beads and so I was annealing soft glass and boro at the same time. As for using old rods there is no danger unless you have a mix of COE’s and do not remember which rods are which. If so then you would need to do COE pull tests to determine compatibility but that is normal.
Currently we have 1 surface mix nortel minor torch and several mapp torches. You can barely do boro work on the minor and not at all on the mapp. If you use any of the soft glasses COE 90 and above the mapp torches work fine just slower.
If you are an experienced lampworker and just want to get checked out on equipment we can arrange something…
Let me know if you have any other questions
