Adding More Glass
We don’t have to stop with a single pressing. With additional glass and pressings the results can get pretty spectacular.
Here’s our setup for the second pressing. Note that we have sandblasted the surface of our first results to ensure we’ve removed any residual kiln wash.
Here’s a close-up:
In addition to more color, we’ve also made careful choices about adding some clear pieces to the mix. The clear glass will cause the color glass to spread more, thinning it out, and diluting the color. Using clear glass this way can provide wonderfully subtle color variation and create vibrant watercolor effects.
We repeat the same setup and firing schedule as with our first pressing, slump the piece over a handkerchief mold for the results shown on the next page.
