I like Germaine"s finegrain in some situations and have a coffee grinder devoted to just PPD, the stuff is always in big rocks and takes forever to dissolve even with my heated stirrer. Interestingly enough, the Germaine's has a purple color if I dissolve the rocks and a straw color if I pulverize the PPD. It doesn't seem to make any difference in the development....EC
