Basic Soap Class
by Lady Dawn Schadue
(from a Class in the Shire of Nahrun Kabirun, Outlands, Summer 2015)
History
A formula for soap consisting of water, alkali, and cassia oil was written on a Babylonian clay tablet around 2200 BC.
About the water
For the water portion, you can be creative and decide to use tea, coffee, herb infused. Always add lye to water, never the other way around, or else we get a volcanic reinactment. Lye will burn skin and rinsing with water does not help, always have vinegar on hand to rinse lye off skin and clothing.
About the alkali
Alkali, such as potassium hydroxide was obtained from the ashes of burned plants.
Soap made from sodium hydroxide (lye) tend to be hard, those made of potassium hydroxide are soft and sometimes even liquid.
About the oil
Any oil, animal or plant can be used. In medieval times, tallow (rendered beef fat) was used. Different oils have differing amounts and types of fatty acid resulting in different effects.
Coconut oil helps produce a lather, pure coconut oil bars will produce a lot of short-lived lather.
Vegetable oil will produce a slick, low lather soap good for shaving.
Olive oil is what is used to make Castile soap or Marseille soap, known for being very mild; hard to get a lather from, but by adding ground oats (colloidal), facilitates the friction needed for lather and is beneficial to dry skin.
About saponification
saponification is the name for a chemical reaction between an acid (the fat) and a base (the lye) to form a salt (the soap).
About the process
Cold process soap uses no additional heat but lye added to water still produces heat. Soap will continue to get harder as it ages since the water is still evaporating.
Hot process uses additional heat to speed up process and may come out smoother to the touch and offer the ability to make soaps that are less opaque (more clear)
Use plastic or glass containers, lye will eat through both skin and metal. HAVE VINEGAR ON HAND IN CASE OF SKIN CONTACT.
Different oils require different amounts of lye. Table provided below for some examples-you will multiply the decimal saponification number by the amount of fat you will be using (in ounces) to know how much lye, in ounces to use.
Coconut .1911
Grapeseed .1265
Lard .1387
Olive .1353
Peanut .1360
Vegetable .1250
Walnut .1353
About the trace
Trace is when the mixture of oil and water have formed a cohesivness and leave a slight mark on surface, leaving a trace.
cold process basic recipe
4 ounces lye (our class will use: 5.7330)
16 oz water (our class will use: 15 oz water)
32 oz oil (our class will use: 30 oz coconut)
1. Pour water component into mixing container.
2. Add lye to water and stir til milky, will get hot.
3. Add oil to water/lye mixture.
4. Still until it gets thick and forms a trace.
5. Pour into prepared container and place out of the way for 48 hours while it sets. Prepared containers can be cleaned out milk cartons, plastic cling wrap-lines egg crates, or even plastic-lined boxes.
6. Flip soap out of container or cut into bars if working with larger block, allow it to finish turning into soap for 6-8 weeks. Some differences in humidity, size, and fat used may shorten or lengthen cure time from 2 weeks to 10 weeks.
