Hi,
A while back I purchased earrings and a pendant which were small circles and convex. The edges were soft and contoured. I tried slumping which definitely didn't work and I would love to know how it is done.
you should be able to slump them, picture would help. What were your firing temps in the slump, also were the pieces 1 or 2 layers thick.

Were you slumping over or in? Janet
