I have a few bottles of test that started to crash slightly. It had some white crystals floating around in it. I took the bottles and held them in hot water, and watched the crystals melt. I used a pan filled with water on the stove. Well, I am wondering if by heating them up as described, I might have damaged the test. The water wasn't outright boiling, but got pretty close. And I held each on in the water for a while. Any info appreciated!!
