Doc

Lots of variables. What look do you want? How rounded do you want the edges. Is the tin side down (it should be). I would fire to 1420 with a 20 - 40 minute soak. Lower temp with longer soak yields a similar look to a higher temp and short soak, but the bottom comes out cleaner. I would ramp up to 1000 in about an hour or hour and a half, soak at 1240 for maybe 20 or 30 minutes and go to top. You don't say what thickness I would probably soak at 1000 for a half an hour to an hour, take that same time down to 900 than 3/4 of the time down to 700 and that same time down to 300.

Get well. Fire when you are thinking clearly.
