So I’ve been testing Crystalline Glazes to use later for the special forms that will be inside my portrait busts. This weekend I unloaded my first test kiln and it felt just like Christmas! I began with four different bases and used a single colorant (copper carbonate) just to see how each would react. I now have two bases with great results to continue testing with different colorants. From left to right each photo represents copper carbonate percentages of 0%, 0.75%, 1.5%, 3%, and 6%.
This had nice large crystals with clear visible backgrounds.
This came out with nice uniform coloring, but the microcrystals were too small & caused everything to go matte.
This last one was the most interesting because something in the base caused a bit of yellowing in the colorant. I liked it because it also had very clear large crystals with a good background.
My favorite’s so far are the results from Dan Turnidge’s & Helen’s Bases. I cannot wait to see what the other color combinations bring out on my next batch.
