Be sure to achieve the optimum temperature when making your candles. This mini thermometer is ideally suited for beginner to advanced candle makers, it is compact, fast, and gives a reliable reading.
The non-contact infrared thermometer infers the temperature from a portion of the thermal radiation emitted by the object being measured, IE it measures the heat coming off the subject, in this case wax.
It is vital that the wax is not overheated at all, and that the fragrance is added at the optimum temperature, as well as poured into the container at the optimum temperature.
This will ensure that your candles have a smooth top finish and will help limit concaving.
