if you are. I could use some cullet if it fits 96. Have a 4 pot electric color furnace. Looking for a milk white.

I have been told it is very dangerous to use so I am trying to avoid it. Is that the consensus with the board here?

I've heard the same thing . But at my age and good ventilation not much of a concern for me anymore . I just want A good strong white that I can dip a hot gather. When I was making my own batch I loved my Fenton white. I have a dead on 96 milk white formula but I just don't want to mix batch anymore . So I'm using Spruce Pine . And while the clarity is not as good as the old batch I used to make myself it's convenient and does a nice job . I do hate buying white rod at such high price and I miss having a pot to dip on. I do know that when you first open the furnace of milk white you don't want to be breathing it in right off the bat . But @52 I don't really care anymore LOL .

George does not care. George wants to blownglass!

I like it. :)

George will fry his electrical elements if he puts a fluorine in the pots. If you think it no longer matters at 52, I'd reconsider that.

I wonder if one couldn’t make a sealed element inside quartz tubing. Considering flourines melt so low.

Fluorine would still attack the quartz. I think anything that can isolate the element from the gas would help. The white is not much of an issue to melt. Doing Cad sel stuff is more problematic. Cad sulfide always resisted complete melting, always from the cadmium compound side. Drawn from the pot at 200 F it looked a lot like crabs legs. It did melt in eventually and resisting turning it up to do so was a fine tightrope to walk. Too hot, the pot dissolved. Too cold, hard to get the melt just right.

I think the furnaces which are essentially muffle furnaces work best with a seal around the top of the pot at the door. Then, the elements are isolated. At that point the heat has to come through the pot walls and you are back to what Durk described with Anti''s melt problems. But it's still better.

Ideally, I'd melt fluorines with gas. After all those years of the moly, I confess it's really nice to be back to serious horsepower from propane. Nat gas would be even nicer.
