Cocolivo Soap
makes 2 3-oz bars

21 g lye (NaOH) ±0.5g
43 ml (3 Tbsp) very cold goat milk or water

96 g olive oil
48 g lard
16 g coconut oil
    = a total of 160 g fat ±0.5g
plastic water bottle
paper cups

WARNING: lye is dangerous. Heed the warnings on the label. Use gloves,
protective clothing, and eye protection. Don't breathe the fumes. Don't use
aluminum utensils or containers.

Measure the lye and fats in separate containers very carefully.

Melt the fats gently, in the water bottle (or melt them and then put them in
the water bottle). Put the milk in a pyrex measuring cup.  Slowly pour lye into
milk. Stir until well-mixed. When both the fats and the lye are about the same
temperature (their containers are warm to the touch), pour the lye mixture into
the bottle with fats, and replace the cap securely. Observe that the water and
oil separates like Italian salad dressing. Shake vigorously until the mixture
becomes white and creamy (a couple of minutes). Periodically check for
separation and shake again. 

Once it has stopped separating, your work is done. When it has thickened
considerably, this is called "trace". It may happen right away, or it may take
a couple of hours or even days of intermittent shaking, depending on many
factors. But if you weighed the ingredients carefully it will happen. Pour it
into the paper cup molds, then set it aside, out of the reach of children, for
2 days. Remove from molds and allow to cure in a dry place for 2-4 weeks.
