this explanation and idea is great. i think i'll try out the base recipe + %wedge approach with a mystery ash glaze triaxial batch i mixed up a while back and then combined together and want to recycle and put back to use, :).

[@marcmancuso]

this sounds like a great application! So glad you like the idea. From my experience with runny ash glazes, I'd say you might need to make volume of the sample big enough to dip a tile in the sample and coerce it to run, to show you it's character. Flat tiles could be painted, but might not alert you to the most runny results that you can (probably) exclude. Good luck. I'd love to hear how it went.

@@marcmancuso :D .. added you on insta. will tag you when i do it!

Great idea Mark. In this method how do you account for the absorption of the glaze into the clay before you remove the divider and mix together? Or is the assumption that the color blend will be close and you will need to tweak the percentages to get an exact match?

[@marcmancuso]

Hi Marc--thanks for the comment! Absorption is absolutely important to avoid with such small amounts. I used wet clay, while I wait to develop things with non-absorbent materials like actual plastics. Wet clay doesn't absorb much, but annoyingly wants to ADD particles while mixing. Leatherhard clay, or dry greenware would be even better, especially if you sprayed it with mold release or something similar. It wouldn't last very long, but my bait for users is that it's worth it to scout around with something that costs nothing.The colors are only in the grooves for a minute or two, regardless of how wet the clay is. Not much will happen that would throw off the overall gradient. To get percentages, measure the length of the entire groove, and then one of the colors.

@@marcmancuso Makes and love the idea as I am WAY to lazy to do a traditionally triaxle color blend.

@@marcd4992 stick around. I was a little shocked myself when I figured it out. I did it the "old" way exactly once.
