This wax melting furnace holds 8L/10L/20L of molten wax, allowing you to make multiple candles at once without frequent refills of solid wax, effectively simplifying and speeding up the candle-making process. The rotary control knob allows for precise temperature adjustment from 30-100℃/122℉-212℉ to meet the melting point requirements of different waxes, and automatically enters intermittent mode to prevent overheating or burning. The upgraded heating element drain valve ensures smooth flow of molten wax. You can easily open and close the drain valve to pour out the molten wax and prevent it from solidifying and clogging the nozzle. Rapid and even heating allows 5 pounds of wax to melt in just 15 minutes at 100℃/212°F, eliminating long waits and providing the convenience of quick results. The transparent glass lid allows you to observe the melting process at any time. This candle melting machine has a small footprint and can melt various types of waxes and soap bases, such as soy wax, beeswax, palm wax, coconut wax, paraffin wax, and jelly wax, as well as glycerin, goat milk, and shea butter.
