Hello All,

I have been drying flowers using silica for about 5 years now. I have about 50 lbs of Auctiva brand silica in the large cans from Michaels Craft Store. Over the years I have dried my silica for reuse maybe once a year. The silica is no longer turning colors to indicate moisture but I dried it anyway in the oven after having a bad experience with some roses molding and not drying. Immediatly after drying the gel in the oven the last time I tried to dry another batch of roses and the same thing happened. The silica clumps like snow on the petals and the flowers rot inside the silica rather than dry. I haven't changed the canisters that I use or the location in which I place them. I followed the instructions for reactivating it. Do you have any ideas? I am really at a loss here and I would hate to lose any more flowers or this much silica. Thank You!
