- 380g tallow
- 5 oz water
- 86g store bought lye (WAY too much due to miscalculation)
- added the lye to the water and let it cool.
- melted the fat completely and let it cool for a minute or two
- combined the two and mixed lightly
- poured into a glass container and set aside to cool overnight.

|Lye and Water Mixture||Melting before adding lye||Unseparated result|
- melted it over a stove
- added a cup of water (to aid in melting)
- added a cup of vegetable oil (to balance the excess lye)
- left to cool in the metal pot I did the melting in
I also collected about a cup of water and a couple ml of cloudy glycerin
The soap was still really granular, and when I squeezed it I got a lot more glycerin. So I divided it into three balls and wrapped them in cheesecloth, then pressed them. This produced dryer soap and more glycerin, but not much more water.
Next note: Decanting two separated liquids is hard without the right equipment. I think that if I were doing this at scale I'd probably find it useful to make some specialized equipment
Day 6: The balls of soap are still in their cloth and still very slick. I think they're still exuding a bit of glycerin. But they do work as soap.
Day 20: The soap is now hard enough to be considered ready
Lye is hard to find these days. Went to 2 hardware stores, a supermarket and 2 drugstores. No dice. Ordered it from Amazon instead. Easy.
