Hi, I have the hemp and the translucent Stephenson MP base. I do not own a microwave. I tried yesterday to melt around 250 gr in a double boiler and it didn't melt to a liquid. I think the soap didn't reach the right temperature to melt properly and I stirred too much, so there were a lot of bubbles and when poured it was too thick to revel properly the mold shape. Can I re batch it? I plan also to experiment again; I'll use a bigger pot and I'll cover it with plastic film to prevent moisture lost, and I'll monitor the temperature. Can somebody with experience in melting MP in a double boiler give me some more advice? Thanks! Edited to add: I gave it another try. Covered with plastic and just a gentle stir at the midway. It melted nicely in clear liquid form. I added fragrance and a bit of mica and it looks like the mica was not well mixed. I tried to mix it gently but again bubbles formed. Any help? I found the base at a local store and they couldn't tell me if it's working well with mica or not.
