This is notes on a firing of frogs and Hand pressings I did. The frogs were on request from a friend of mine.
I'm not actually certain which firing schedule was used for these molds, but since they were in a kiln that was the final firing of the multi-fire project, I'm guessing it was something like this:
1. 2:00 - 100C
2. 8:00 - 150C
3. 13:00 - 600C
4. 14:00 @ 600C
5. 14:01 - 840C
6. 15:15 @ 840C
7. 15:16 - 540C
8. 18:00 @ 540C
9. 20:00 - 430C
10. 23:00 @ 430C
11. 32:00 - 300C
They were fired in Kiln #1 on October 28th, 2009, and the kiln was unloaded on November 1st, 2009.
All of these were packed with talc-like powder, and the frogs had forest green frit mixed in at a 2:5 ratio. For the frogs, the opaque, bubbly texture that comes with using so fine a powder was nice, it made them look ancient, but I really didn't like it for the hand pressings, it was way too rough, and didn't pick up the high detail of the texture that the ones I did last spring with furnace pellet did. They look to physical for me when they are cast in powder. The clearer finish makes them look more ethereal.
