Preparing your work space before making cold process soap is essential. It helps the process run smoothly, as seen in this post. However, as any soaper can attest, even with the best planning you can forget something. Maybe it’s a colorant, a fragrance, or an oil. Trust me, it happens! Not that I’m speaking from experience or anything. 😉
While forgetting a color can change the design slightly, forgetting an oil can result in lye heavy soap that may burn your skin. The soap can also end up lye heavy if the recipe amounts are off, if the ingredients are mismeasured, if the scale isn’t functioning properly, etc. This creates a hard or brittle soap. It may also be irritating or drying to the touch, or have little white pockets that look like air bubbles. Testing the soap is the best way to know for sure.
