Soap and Candle Making
Rendering fat and leaching lye for soap. Wicking and moulding candles for light.
Soap and candles are essential health and lighting technologies that can be produced from fats, ash, and fiber.
Important
Unreacted lye can burn skin; verify soap has cured fully before distribution.
Key Concepts
- —Saponification needs correct lye-to-fat balance and curing time.
- —Candle performance depends on wick size, fuel purity, and mold design.
- —Rendered fats require filtration to reduce odor and smoke.
- —Product consistency comes from measured batches and repeatable process.
Practical Guide
- 1.Leach wood ash to produce lye and test concentration before use.
- 2.Render and filter fats or oils to remove water and solids.
- 3.Cook soap mixture with steady heat and pour into molds to cure.
- 4.Dip or mold candles with centered, pre-waxed wicks.
- 5.Store finished goods dry and labeled with production dates.
