I had one pot in the center as well as two on either side- I center pot was large enough to hold the amount of glass I needed. Before I fired I was concerned about that.
I now understand the need for a slow advance and how you came up with that.
3 more questions:
Can I do this on thin fire paper since I am firing to 1500 or do I need to prepare the shelf as I did for the pot melt?
Do I need to go on and remove the kiln wash that is on the underside on the piece?
Do I need to dam it again? ( I think yes). I am so afraid to fire that thick a piece w/o one and I have never done a pot melt w/o one.
My firing schedule for this piece was
9999/1540/45 then to 900/120 and a conservative cool down
The first two this week have alot of popped bubbles on surface, not over an 1/8 diameter. Do I refire with top side up to a full fuse1500 with a dam? Using thin fire or heavy kiln wash? Thickness 1/2 inch.
Or do I flip it over and fire to 1500. I would guess at a soak of 30 min
The need to redM is always confusing to me. Thickness again is 3/8 on one and 1/2 on the other
The firing schedule on the ” bubbled” pieces were pretty much the same except 700/1700/90 & soaking at 1500/60
I really appreciate your good explanations and advice. It is nice to know these forums are here and people are so willing to take the time to answer these questions.
