- Water and lye -- always in that order -- are always the first ingredients. He heats a carefully measured mixture of the two until it reaches 115 degrees Fahrenheit.
- Then he carefully measures oil, which must be the same temperature as the lye in order to prevent separation when the two are combined.
Note: Mareci uses only natural oils, which commercial soap manufacturers don't always use. In addition, he explains, manufacturing processes often eliminate the glycerin and oils found in natural, handmade soaps. - He adds a small amount of borax (to dilute minerals in hard water) before blending ingredients with a hand- or drink-mixer.
- Finally, he pours the mixture into a large divided mold, covers it and allows it to solidify and cure over a three-week period. (The curing eliminates any toxicity).
Mareci says all ingredients must be carefully measured in the correct proportions. He recommends that the beginner invest in a good scale (you should see the investment pay off later, as soap can be made for about 70 cents a bar).Warning: Because Mareci is an experienced soapmaker, he can take shortcuts (such as heating the mixture in the microwave) that a novice should never try! Furthermore, he says that vinegar must be available to neutralize the lye, and all utensils should be rinsed immediately after use. Lye is extremely toxic and must be handled with caution -- remember: this is a product that is used to clear blocked drains!
Lye's caustic properties can burn skin, so you must do the following:
- Use proper equipment
- Take necessary safety precautions
- Wear protective attire.
Soapmaking supplies are available through a variety of sources, but you must use proper safety precautions when attempting this type of project. It's a good idea to know what you're getting into before you start: study soapmaking sources such as books and websites before you even purchase supplies.
