【Ideal Size】Its compact size is perfect for smelting small batches, with an outer dimension of 4 x 2 x 1 inches (100 x 50 x 25 mm) and an inner dimension of 3.5 x 1.6 x 0.8 inches (90 x 40 x 20 mm)
【High-Purity & Durable Material】 Made from premium graphite with an ash content of less than 0.1%, ensuring metal purity is not affected during refining. It offers high thermal stability and durability (withstands up to 1800°C/3272°F), and is not easily broken or deformed
【Effortless Metal Release】 Superior self-lubricating properties ensure smooth, residue-free release of cast ingots
【Superior Thermal Performance】 Excellent thermal conductivity significantly shortens melting time, saves energy, and performs reliably under rapid cold and hot use conditions
【Versatile Application】 Ideal for experiments, smelting, and analysis of non-ferrous metals (e.g., gold, silver, copper, aluminum) in settings like laboratories, jewelry making, and small-scale metal processing. Backed by reliable post-purchase customer support
