What is the "Gel Phase"? Does my soap have to gel?

Gel phase is a part of the saponification process that happens after the soap has been poured into the mold where the soap gets hot and becomes more translucent in appearance. This is a part of the soap making process that can happen naturally but isn’t completely necessary. Your decision on whether or not to let your soap gel depends on the result you’re looking for.

How do I blend essential oils to scent my soap?

Creating a good recipe may require trial and error to determine how much of each essential oil is needed to create the aroma you are looking for.
