I used 3 Tbs pp of stearic. I don't know if I could pour any cooler - it was pretty thick as it was - I made some previously where I started pouring at 150, then went up 5 degrees each layer, and they LOOKED a little smoother than these, but fell apart when I tried to wick them. This held together great, but I don't like the looks of it. Ha. I think part of my prob as far as the non-smoothness of the layer adhesions is that I may have been getting my mold a little too cool in between repours (using a wet cloth). I'll give it another shot and not cool it down so much, but I still don't know why I'm not getting the frost I want
