Hello! I’m very new to resin and drying flowers. I have dried somw using silica gel and then put them in resin. However, several of the petals in different casts have gotten brown splotches immediately when put in resin. Were the flowers not fully dried, did the resin burn them, or something else? I tried a small amount of resin the second time, worried about the heat, but it still happened. I thought the flowers had fully dried, but maybe not? Thanks!
