This thermometer provided exclusively by Cosy Owl can measure the temperature of your melting wax between 0°C and 100°C (up to 212F). This highly durable thermometer has been specifically manufactured for candle making. This is an important part of your candle making kit, ensuring the wax temperature is not too low and does not exceed the temperature at which the molten wax could become dangerous. Generlly speaking the temperature should be between 55°C to 65°C depending on the type of wax being used. For more accurate information refer to the 'Temperature Guidelines' under our INFO & GUIDES section of this website.
