These high-density graphite crucibles are designed to be used with our electric MF series, or Hardin melting furnaces. They are slightly more durable than our budget crucibles, maintain good thermal stability against harsh temperatures plus have good thermal conductivity to allow for quicker melting times. Featuring an outer groove so that they can be easily handled with our large stainless steel tongs. *Not recommended to be used with torch method or open flame furnaces.
