Each has its own benefits, but when you combine the processes, you reap the benefits from both. When you are finished creating your cold process soap and have it safely in the mold, you can put it in a warm oven to force the gel stage. After you make soap for a while, you'll be able to compare a bar that has cured for several months with one that has just cured a couple of weeks and quickly tell the difference between the two.
