These are some good ideas, wwrich - thanks!
Mare mentioned something about the silicone (vs. plastic) trapping heat and so now I'm wondering ... perhaps I could "freeze" the silicone molds empty in the freezer for a little bit before I pour the melted soap in? And of course also try to pour at that twilight zone of temperatures - melted but just before it starts to form the skin on top. So stick the molds in the freezer, melt some soap, and then pull the molds out of the freezer to fill. Leave them out and see?
I did try to wet and rub/buff the top and they have improved, but I can still seem some "specklies". I'll try some of these ideas tomorrow and report back! Thanks for all of the advice so far
eta: oh I meant to mention that the silicone molds I have feel really smooth inside. I had a different kind before that felt a little rougher, but the soaps I'm creating now are actually very very smooth, just cloudy
