Heating to 2102degree(s)F/1150degree(s)C in about 45 minutes, this 1350W furnace melts gold, silver, aluminum, and copper with a spacious 3 kg capacity. A high-temperature ceramic chamber, quartz lid, and ceramic crucible work together for efficient, even heat retention, and the crucible's grooved design makes pouring and filling precise. Temperature stays reliable thanks to a Pid module, digital control system, and K-type thermocouple that read the chamber every two seconds within 1degree(s)C. The kit arrives complete with 1 kg and 3 kg ceramic crucibles, an ingot die, crucible tongs, a power cable, and high-temperature gloves, so beginners and pros can start right away. Measuring 14.96 x 9.45 x 8.27 inches, the smelter fits neatly on a workbench for jewelry, workshop, and industrial metal refining.
