How to choose a wick for paraffin candles

How to choose a wick for paraffin candles should be read as a practical material guide, not as a promise that one wax solves every candle-making problem. Paraffin is widely used because it is consistent, easy to colour, compatible with many fragrances and predictable when the maker controls temperature, wick size and container choice.

Material context

Paraffin is a refined mineral wax. In candle making, its value comes from repeatability: makers can test a formulation, record the variables and reproduce the result across small batches or larger runs. The important question is not whether paraffin is universally better or worse than another wax, but whether it fits the candle format, the fragrance load, the vessel and the expected use.

Wick choice

Wick choice depends on diameter, wax grade, fragrance load, colour, vessel and desired melt pool. Start with the supplier range, then test one size down and one size up before scaling.

What to observe

A wick that is too small may tunnel or leave wax on the sides. A wick that is too large may create excessive flame height, heat or soot. The correct wick is the one that behaves steadily in the tested candle.

Safety and testing

Use paraffin with normal candle safety discipline. Work with moderate heat, keep the melting area ventilated, avoid overheating, trim wicks during testing and never leave a burning candle unattended. Soot, smoke and uneven burning are usually linked to wick size, fragrance load, airflow, vessel geometry or poor testing rather than to one variable in isolation.

A useful paraffin test records melt temperature, pour temperature, wick model, vessel diameter, fragrance percentage, cooling time and burn observations. Small test batches are more reliable than assumptions, especially when changing colour, fragrance, mould or container.

Internal path

For the material page, continue with paraffin and candle wax. For process basics, use candle making. When the question is flame size or burn pool, compare with candle wicks.
