HIGH QUALITY MATERIALS: Our molten metal crucibles are made of high quality fused quartz using advanced ceramic processing technology. These crucibles feature exceptional heat resistance up to 3272°F / 1800°C ensuring reliable performance during high temperature melting processes. The stainless steel handle is comfortable to hold and easy to operate. Multifunctional set: The set includes four crucible trays (two each of 250 g and 100 g) and two stainless steel pliers with whip handle 2A, providing all the necessary tools for precise and efficient metal melting. CONVENIENT DESIGN: Our crucibles feature tapered sidewalls and pour spouts for easy material removal and increased user convenience. Wide range of applications: Our crucibles are suitable for various precision casting processes involving metals, , gold, silver, copper, brass, alloys, etc. IMPORTANT: To optimize the performance of your quartz ceramic crucible, we recommend slowly heating and applying a borax glaze before use. Following these steps not only produce the best results, but also extend the life of your crucible, allowing you to maximize its value and effectiveness.
