Abstract: A thermochromic colourant is used to indicate a temperature change in a candle. During manufacture, the colour change of the colourant will indicate when the temperature has fallen to a level suitable for packing of the candle. The candle formulation may include the thermochromic colourant to visually indicate when in use parts of the candle above a predetermined temperature, or the colourant may be provided in a coating on the candle body, or in a wrapper for the candle.
