I'm sorry-- I thought I had replied to this question.

I used mason stains and white porcelain. I decided how much clay I wanted to use (I believe this bowl was two pounds-- just a little one) and split it into four. I had three different stains, and I wedged one of each into one of the pieces of clay, leaving one unaltered. After each individual color was very well mixed and each piece of clay very well wedged, I put the four pieces back together and wedged until they were just mixed. 

I'm actually kind of compulsive about the number of times I wedge things. I usually do 108 times, but I only did 32 times for the final combination.

After that, I let the clay sit for a while-- I mixed up a whole bunch of it and then used it over the course of a month or two. Before I threw it, I wedged it another 32 times-- just enough to soften it up a bit. After that, I threw it just like I normally do until the last bit.

At the end of throwing, before I took it off the wheel, I used a thin metal rib (mudtools metal scraper) to take off the top layer of clay and slip, because that gets really mixed while throwing and makes the contrast harder to see. I trimmed the bowl like I normally do and then used a clear glaze on the inside. The clear glaze helps bring out the color, I think.

I'm still just starting out with this technique, and so I'm still a bit overly cautious.

could you explain how this was done?
