Hi Min and Jeff
thank you both. I used Silica sand under them ( I stacked about 5 on top of each other) when I first bisqued them and everything was fine. I then refired to 1220 same way again but nothing between the pieces and they all fused together slightly. I was able to get them apart but broke a couple in the process.
I am wanting to go straight to 1220, not a seperate bisque and higher firing, but wondered if I can put the sand in between the pieces without them effecting them in any way. I imagine it will just dust off?
Jeff I like your idea but I think it might be a bit difficult as the pieces are like pages of a book, very thin and hard to do top and bottom I think.
