Kerr Graphite Crucibles 29478-35620 For All Kerr 30 Troy Ounce (1 Kilo) Standard Electro Melt Models
Long Lasting Top Quality Virgin Graphite-Made Exclusively for Otto Frei-Last Longer-More Economical
Graphite crucibles provide maximum resistance to oxidation while metal is being melted. To avoid contamination use a separate crucible for each metal.
This graphite crucible is made from virgin graphite, not compressed graphite, as so many other graphite crucibles on the market are. Our graphite crucibles are heavier then others with a bright shiny smooth surface when new. Same pattern as Kerr part number 29478 and Kerr part number 35620 . Used in all Kerr 30 troy ounce gold ( approximately 1 Kilo) Electro Melts from the current model 35222 and including the following earlier model numbers:
Kerr Series 1258 (former production)
- Kerr 31806 120V
- Kerr 31807 230V
- Kerr 31808 120V
- Kerr 31809 230V
Kerr Series 364 (former production)

The outside measurements of a brand new Kerr 30 troy ounce (1 Kilo) capacity gold graphite crucible is 5" tall by 2-1/4" wide (measured at widest point). The crucible measures 1-5/8" wide below the lip. The crucible is 4-1/8" tall measured from bottom to top of "lip". The inside dimensions are 1-3/8" across by 4-3/16" deep. These dimensions will change as the crucible is used, as the graphite will wear as it is exposed to heat and air.
