Comprehensive Kit for Craft Enthusiasts: Our melting casting set includes 2 graphite stir rods, 2 graphite casting molds, a versatile 5-in-1 ingot mold, a quartz crucible, a cylindrical graphite piece, and a handy tong. This selection is specifically curated to support a of melting and casting projects. Optimal Performance and Durability: The components of our kit boast superior thermal stability and excellent thermal conductivity. This enhances the efficiency of the smelting process by speeding up cooling, reducing casting time, and simultaneously conserving energy. Versatile Usage Across Projects: Designed for the smelting of non-ferrous metals such as gold, silver, copper, and aluminum, these tools are perfect for small-capacity projects. They're also suitable for laboratory analysis and other precision work in scientific settings. for Enhanced Melting Experience: The graphite molds and crucible included in this set are designed to handle high temperatures up to 3200F when used in an air electric furnace, ensuring reliability and under intense heat during metalwork. Care Instructions and Usage Guidelines: To maintain the integrity of the pure graphite components, do not use in a carbon furnace or charcoal kiln as they may oxidize and crack at temperatures starting from 752F. Ensuring proper usage will extend the life and performance of this melting kit.
