Outer size 3.93×1.97×1 inches, inner size 3.54×1.57×0.78 inches. Holds up to 1kg of gold or 530g of silver with a 2.43 fl oz volume, meeting the core needs of small-batch metal ingot casting.
Made of premium high-purity graphite with less than 0.1% ash. Resistant to breakage and deformation under high temperatures, it ensures metal purity during smelting and extends mold service life, suitable for repeated high-temperature smelting.
Superior thermal conductivity significantly shortens metal melting time and saves energy. Withstands up to 1800°C (3272°F) high temperature and rapid temperature changes, ensuring stable smelting without mold cracking.
Ideal for melting and casting non-ferrous metals like gold, silver, copper and aluminum. Suitable for jewelry making, metal experiments in labs, and small-scale foundries/workshops, easy to use for both beginners and professionals.
Equipped with excellent self-lubricating properties, the ingot releases smoothly without residue adhesion. Easy to clean and reduces subsequent grinding procedures, improving the overall efficiency of metal casting.
