Wax melters are devices used in the packaging and candle-making industries to melt wax. Wax melters are devices used in the packaging and candle-making industries to melt wax. The type of tank used to melt candle wax is quite different from adhesives, solder, and tar. For example, tanks used for adhesives may need to be heated up to 260 °C (500 °F) whilst an organic soy wax will be ruined at over 60 °C (140 °F) and should never be heated above 93 °C (200 °F). A delicate soy wax used to make candles would be destroyed and burned if not heated in an even manner at lower temperatures than solder or tar. Also, since soaps and candles are scented and coloured, tanks designed for melting these substances need to be specially polished to ensure there is no contamination between different scented/coloured candles or soap. For this reason, there are melting tanks that are specially coated for candle wax melting.
