You got a bad packet of Xtol. It should NEVER do that.(posted 8768 days ago)Kodak had some problems in the past packaging their Xtol developer product. If the powder is clumpy or more of a solid mass, you can send it back to Kodak and they will send you a good packet. They want the plastic package with the lot code on it.
When Xtol is good, the part A will form a pink color, and the addition of part B will result in a clear solution. Just follow the directions: Start with part A and slowly pour it in while stirring, then do the same with part B. The water should be 68F to 80F. I mix at 80F because the chemicals disolve quicker, then I leave it overnight to cool. The water I use is filtered. You might try using distilled water.
Personally, I would have saved the crystal, boxed it up, and sent it back to Kodak. I'm sure they would have loved to analyze it! (Actually, I would have photographed it first. It sounds neat!)
