A molten gold writing apparatus that includes a barrel extending from a top end to an open bottom end. A heating element is positioned within the barrel and includes a rechargeable battery. A cartridge includes a refillable chamber configured to hold a solid gold refill and dimensioned to fit within the heating element. The heating element melts the gold refill and allows it to flow to a tip end of the cartridge. A grip is configured to selectively engage the bottom end of the barrel to cover all but the tip end of the cartridge.
