I did some experimenting with dyeing faux clays and I'm not thirlled with how they turned out, but it does prove a few things, and I'm sure some other CTers can perfect the method used. Personally I like the solid colors better and I don't plan on doing anymore serious "experimenting" so I thought I'd share what I did.
I used the kool-aid method of dyeing, with kool-aid and hydrogen peroxide, and after dyeing a chip one color, I painted edgespots with rubber cement, then dyed the chip again. Since the dye method was cold, the rubber cement did not melt or run into irregular patterns.
Afterthoughts:
1. I like edgespots that are more precise and symmetrical than the results I got. If I do try again, I will use a foam brush to apply the rubber cement because its tip is more square and uniform than the brush the rubber cement comes with.
2. Dyeing one color on top of another does mix the colors, as was questioned in another thread. The green on green chip was dyed green, then blue, and it came out green on green.
3. Using Lemonade kool-aid does not give the best results. I didn't try it a second time with more kool-aid per hydrogen peroxide, but my first two tries only made the chip an off-white color. The orange chip's edgespots were supposed to be yellow, but as you can see, it is almost identical to the white on the blues, which was not dyed.
All in all, nothing fantastic, but I felt I should let fellow CTers know that it could be done, since I don't remember seeing this anywhere else. (If it is, I am sorry.) If you like irregular edgespots, then you might like these, however it would be a real pain to make an entire set of these with edgespots!
