Hello! I am a new soapmaker and this is also my first time joining a forum of any kind. I just completed my 2nd batch of CPOP soap. Both recipes were olive oil/palm kernal oil/coconut oil and castor oil. The first batch was rosemary mint and this last batch was grapefruit jasmine. I used a silicone loaf mold and put them in a 170 degree oven for one hour. I let the soap sit overnight and unmolded the next day. Both batches were covered with a light skin of very tiny bubbles. It made the soap feel a little gritty. when I cut the soap, the inside was smooth and hard. Does this always happen with CPOP? Is there a way to stop this rough "skin" from forming during CPOP? Is there a way to remove it without shaving the skin from the soap? Polishing cloth? Thanks!
