I have found the seamless ring idea very interesting, It's
easy, it's simple, practically it's an old idea from the casting just
transferred to clay world. Well... I'm
probably very cheap, or just like to make my own tools:o) but I just can't justify the price of this
new/old invention. The piece of foam for 25$ it seem too much. So I decided to
make my own:o)
1) I've made ring 2 sizes bigger than needed from the
polymer clay, baked it.
2) cut two pieces from foam brick and pressed 1/3 of the
ring into the foam. Put on the second piece and pressed both together, so now
ring had imprint into both foam sides. Pierced with craft sticks both foam
pieces to secure placement. Painted/Applied epoxy resin to the foam. Cured.
3) Made my one seamless ring. Dried one side. Took off the
mold, finished drying.
4. Sanding, carving, firing. Strange but all rings from all
4 metals ended up with different sizes and shrinkage (all of these metals were
supposed to had shrinkage of 8-10% and all
had been made from the same mold)?! All of them were fired separately, according
to specific metal temperature. Strange?!
Steel, bronze, copper, white bronze. Initial size of the
mold 10. Do I like kiln surprises? Not sure?!
