I recently made a batch of carrot ginger tumeric soap that came out with a lovely color. I added ginger essential oil as well it smells wonderful. I then put it in the oven to accelerate the gel process but then take it out because I needed to do some baking. I then put it back overnight to finish the gel process but next morning there’s a discolored rough film over the surface and it’s not soda ash except for one bar Thad completed the gel process. How can I fix this problem?
