1. Would it work to put a ceramic bisque tile under the glass on the kiln shelf- then the silver would leach onto that and not onto the kiln shelf? (I also do pottery and make my own texture tiles for glass fusing)
2. Is the three times firing required to remove the leaching because a glass kiln doesn't get as hot as a ceramic kiln? If so, I am thinking I could just put my bisque tile into my ceramic kiln and make it hot- up to cone 05 when I am doing a bisque fire for my pottery, and the silver would be leached out. Since silver melts at 1763F, and cone 05 is 1915F.
3. Am I understanding correctly, that if I were to fuse with silver again using the "designated shelf- it could leach onto my new projects until the shelf was fused 3 times without any glass project on it to get out the leaching? (which is why I think making a stack of bisque tiles to use under my projects would work because then I could just take all the "used tiles" and fire them bisque again and get the silver out and then make more silver/glass projects.
