Clay Gray Crucible or Graphite Foundry Crucibles are made from a combination of graphite and clay, these crucibles are recommended for melting your precious, or non-precious metals and can handle large batches of material. Their thick inner walls can handle direct heat and open flame foundries. Rated to withstand temperatures up to 850ºC-1600ºC.

> Store crucibles in a dry , warm place or wooden palate
> Do not stock inside another
> Do not roll crucibles
> Use creramic fiber blanket to seal , interspace of cover and sides of furnace
> Use locating bricks in tilting furnaces,to interspace of expansion
> Tangential fire around crucible
> Add flux after metal is molten
> Avoid premature crucible failure by ensuring that the furnace drain hole is sealed
> For lift-out ,tongs must be placed on lower third crucible . fit tongs evenly on both side
> Check for cracks or other damage during transporting before use
> Base block must be flat , larger than crucible bottom and centered
> Use tongs and ingots should be placed carefully into the crucible
In order to protect the glaze layer of the crucible, handling crucible must be very careful, to avoid knocking, collision or falling, we can't put the crucible on the ground and rolling to transport. Once the glaze layer of crucible is damaged, it will lead to oxidation and aging of crucible easily in the process of use. The crucible should be handled carefully in a padded cart (or other suitable conveyer).
Our company use rope, rubber, moisture-proof plastic paper, shockproof to pack the crucible, and according to customers' needs, we can customize wooden cases, export packaging cartons, paper tubes, etc., to ensure that the crucible wouldn't be damaged in transit.
The crucible should be protected from moisture. The warehouse for storing crucibles should be dry and ventilated, and the temperature should be kept between 5ºC~25ºC, and the relative humidity should be 50-60%. The crucible must not be stored on brick soil or cement floor to avoid moisture.
