How to use stearic acid for candle making

How to use stearic acid for candle making is a practical guide for candle making. Treat the ingredient as one variable inside a complete system: wax, wick, container or mold, temperature, dosage, supplier instructions and repeatable testing.

Context

Stearic acid is used in some candle formulas to adjust hardness, opacity, shrinkage, mold release or burn behaviour. It is not a universal upgrade. The result depends on wax type, percentage, temperature, container or mold and wick choice.

How to use it

Follow the supplier rate and melt it fully into the wax before pouring. Use small percentages first, then compare hardness, surface finish, release from the mold and burn behaviour against a control candle without stearic acid.

Testing and workflow

Test in small batches before repeating a formula. Record wax type, temperature, dosage, wick size, container or mold, curing time and result. Change only one variable at a time.
