There is still a lot of trial and error with resin for me. I love this ring, but it is rubbery so I have to recast it with the correct catalyst to resin proportion, also the back is flat but that's nicer than the many tries I did as a 3d cast instead of a flat cast. Also it is too big. I was making some dripped resin layered rings before this, so I thought adding material was the easy direction, but for a cast item I think it will be easier to shave off material. So I can cast this in beeswax, which shrinks as it cools, then make a fresh mold in 2 part silicone, then cast it in resin that I've mixed properly.
I figured out a one piece cuff link I'm happy with! I made the original out of buttons and cheese wax. And I can cast it in any color! But the mold is only usable once or twice, because I make it thin and then invert it to release the cuff link. I just made a thick mold and cut a zig-zag down the side to release the cuff link, but I haven't tried it yet. I'm hoping it will just make a thin seam of extra resin that I can trim off. Maybe I can let the resin set in the mixing container for a short time to thicken.
I love waiting overnight to decant these little treasures. Maybe I should take notes instead of trying to remember what works.
