Small soap dish slump mold
Slump firing schedule:
300dph................................1250 degrees..............................hold 10 min
Full........................................900 degrees..............................hold 1 hour
100dph...................................700 degrees..............................off
Uneven edges, it is hard to cut both layers exactly the same.
So I tried another one with two layers of glass: one layer of 3mm clear glass, capped with thin 2mm green glass. I fused a stenciled design on the top of the piece of a yellow flower with black center and bright green stalks. I am currently fusing that piece with the following schedule, hoping that the ripples, slight though they are at the edges, will show up. So in order to achieve that I used the following firing schedule:
300dph...............................................1150 degrees.......................hold 10 mins
300dph................................................1220 degrees......................hold 15 mins
Full........................................................900 degrees......................hold 1 hour
100dph...................................................700 degrees.....................off
Hopefully this will pick up the edges in the mold, ever so slight but still nice. I still have not been able to reproduce the effect in the picture below. Will be able to extrapolate to other difficult slumping molds what I have to do to pick up all that they have and I get to learn a lot as I go on.
I am going to go back to making some unusual frit combinations and filling the mold with that. The stencil worked okay. In future tries I will work harder to get the design sharper, more precise, fill in spaces on stencil with more accuracy.
I like the one I previously made with clear frit mixed with other colors and the frit is not fine, it is at least medium so I can see little balls in the "cast leaf". Although the mold is in the shape of a leaf, it is also a soap dish so it is plenty deep and not a delicate cast glass piece. But I am trying to make it that way and fired it as a thin cast piece using the following schedule:
300 dph......................................1375 - 1400 degrees.....................hold 10 mins
I used 1375 degrees processing temperature, because it is good to fire it low at least to begin with.
Full...............................................900 degrees.............................hold 30 mins
Off
