Fmueller (one of the many people here) uses it. He told me that he had to contact 3M to find a distribution center. He said he tried calling pool places but they never heard of it. As far as cost, he told me it was less than half of Tahitian Moon Sand and completely safe. 3M's website says that the ColorQuartz is quartz crystal with ceramic coating. I would suggest you start at the source. I'm looking for it myself. What color are looking for...could it be....black?
