The Powderscales-deluxe-plus will probably cause a visit from the drug squad. (Joke).
We used scales like that when we used to load our own Ammo.
A project for next week. :D
If you’re going to make your own soap, or soap to sell or give away, I strongly suggest that you look up soap making on the Internet, and join groups that discuss soapmaking. Buy the books that they recommend and read, read, read about it.
You can learn by doing, but if you have to discard a ruined batch, it can be an expensive and messy proposition.
The instructions I posted are totally bare bones, and you will have to learn a bit about chemistry and the properties of the oils that you use, such as their saponification values.
You will have to calculate how much lye to use, depending on the oils, which have different “sap” values. There are lists of sap values online. After you master that, you can also go online and use the many lye calculators that are available to check your numbers.
It takes time, study, and good friends on the soap-discussion boards, but if it’s something you want to do, the work is definitely worth it.
That first perfect batch (which takes about 6 weeks to cure if you use cold process) will be your reward when the smooth, creamy suds and lather appear as you wash your hands with it for the first time.
If you go hot process, you can use the soap the next day, but I prefer cold process because it’s easier to pour into individual molds.
