I use the microwave all the time for melting my soap. I set it for 2 minutes. Then stir. Do another minute. Been doing it this way for about 7 years now. The microwave is fine.
I at least get a full melt pool on the first burn. If the container or pillar is 3" in diameter, then at least 3 hours for the first time. I usually go longer on my burns if I'm going to be home all day.
Been there When you get it too hot and it crumbles, remelt it with some added water or glycerin added in. I recently had to do this...works like a charm. I added glycerin to mine. Made a nice creamy bar of soap with lots of lather.
Here's the guideline I use: Water 75% Honey 2 % Stearic Acid 2 % Oils/Butters 15% E-Wax 4 % Preservative 1% Fragrance Oil 1% Heat the water and honey together in the microwave. Almost to boiling is what I do. In another container heat/melt the stearic acid, oils/butters and e-wax together in the microwave. Pour the water mixture into the second container. You can use a stick blender, mixer or stir by hand until all is blended. During the cool down phase add preservative and fragrance oil. Keep stirring until totally blended.
I use the low sweat cp like melt and pour base. I'm wrapping in paper with no problem. I also put the soap in a shrink wrap bag (left open and not shrunk), then put that in an organza bag. I leave them out for a day or two before wrapping. Been doing this for about 7 years now.
Thank you both. The color is chrome green oxide mixed with the oils before putting into the soap base. I usually mix mica and oxides with glycerin, but the oils were in front of me.
This is my first time using a wood soap mold. I tried really hard to get the bars the same size, but that didn't work out so well. I added Shea Aloe Butter, FCO, and OO to the base (low sweat cp like melt and pour).
