Was doing some reading this morning and came across some articles about the history of Potash and manufacture of chemical. Really simple process quite actually. It starts with wood.
- Make a fire pit or use your grill. Be sure you clean out any old ash or material.
- Line with several layer thick aluminum foil (this just makes handling the ash easier)
- Burn wood
- Let ash cool but not get wet (don’t leave over night for dew)
- Place ash into water - I was thinking a 5 gal bucket with 3 gal water. Add 2 gal ash and stir gently.
- Let sit over night.
- Filter solution - insoluble chemicals will settle to bottom and float on top.
- You know have a Potash solution of unknown strength. Boil down to create potash flake. It was not be 100% pure. If you repeat the mix with water, boil process then you will end up with highly pure (say 90%+) potash flake.
Between all the BBQ Smoking I do and land clearing, I figure I should have a ton of wood to bun. Gonna try this when I get home and see how much produces from a certain amount of wood. If it only produces a few pounds, still, free potash, just takes some time.
Anyone try this or do it already?
