Gabbert g-12 casting in progress
Posted: Fri Mar 28, 2003 10:31 pm
The spelling is going to be bad, and this is partial info, and I do have to go back to the basement and charge the pots.
first: 1400 is not enough for "swift" casting. I slept with it at 1400, and it DID empty the pot, but not with speed.
1600 is too much for a 18in mold. 50/50
1550 is really nice. it takes about 2 hrs to empty the flower pot of a (32oz) scoop charge. You can travck the progress with the pyrometer. Once the pyrometer goes back to 1550, then wait another X minutes, and it will empty.
Carol knows about my "pipes". All I can do is about 18-20 inches, adding on the flower pot. Pot suacers are Useless, or close. When you get that "walk in" annealer together, send me a pic.
Shutting off the kiln when charging is , just a relief. try it...
Steph: FHC is Fenton Heavy Crystal, for whoich there is a waiting list. I have no idea "What" it is, except there is a waiting list. The fact that the G-12 anneals around 1000, tells me that it's not that far from soda lime. Not that it's bad...
G-12 Pate: Don't do it. Unless you like bubbles and/or extended firing times.
