Clay Graphite Crucibles

Clay graphite crucibles are primarily used in melting operations, and are suitable for use up to 3,050°F. Clay graphite represent a good value, have excellent thermal shock properties, and are generally the choice for melting precious metals in melting furnaces. This series is the small capacity crucibles for melting small quantities in laboratory size furnaces. Below are general dimensions and capacities.
