CPOP is kind of like a hybrid between hot and cold process. Make your normal CP soap. Throw it in the oven and you bake it at a low temp for 1-2 hours. However, you must make sure that your mold can withstand the heat .. you don't want to start a fire. Leave it in the oven over night (built in insulation). I use it to force gel which makes for a more consistent color. You have to be careful about the flashpoints of your fragrances ... I generally go between 180F but depending on the fragrance I sometime go lower. I do not use CPOP for any type of dairy soaps (coconut milk, GM, yogurt, etc).
It is ready to use as soon as it cools and you cut it .. BUT it still needs a cure to get nice and hard. I've found that it shortens my cure time by a few days, but nothing major (it's not like it cuts your cure time in half). I can't remember where I heard it, but I've heard that the higher the temp at which you cook the harder your bars get .. and faster .. I don't know if it's true .. I can't vouch for it as I only use CPOP to force gel to make sure I get a nice consistent color.
