Ingredients:
- Crystal drain opener (15 g or more)
- Oil (100 g or more)
- Water (30 mL or more)
Use preventive clothing (goggles, lab coat or thick apron, gloves) and cover all your skin to prevent effects of probable accidents.
- In a bowl, crystallization dish or a similar container, weigh 100 g. of the liquid oil (if not liquid gently melt it and keep as melted).
- In a cup weigh 15 g. of crystal drain opener (or caustic soda, or sodium hydroxide, or potash).
- Add 30 mL of tap water and shake (or stir) until all solid is dissolved (CAUTION: solution gets hot! If not handled properly this hot solution may burn your skin both from the heat and caustic effects. BEWARE!). While still warm pour it into the liquid oil.
- Stir with a spoon (or a magnetic stirbar) for about 15 minutes (or until tracing occurs – tracing is the visible tracks of stirring).
- Let it sit open to air in a hood (or ventilated area) to dry and cure for couple days (or a week).
If you don’t have access to Crystal Drain Opener or lye or NaOH or KOH, use this method: Potash from burnt wood
