How to use

1.The crucibles should be put on the pallets instead of the ground and stored in a dry place with good ventilation.

2. Use the proper base to support the crucibles. Attention! The base should be with a bigger diameter than the crucibles’ bottom and with the same material as the crucibles’.

3.Make sure the furnace lining works well .Make sure the crucible and furnaces are concentric.

4. Use pincers to put the metal into crucible carefully
