Talking about crucibles - How to properly temper a crucible?

In todays video I will show how to properly temper a crucible. I did not properly temper my older and cheaper crucibles, but with this expensive and top of the line salamander crucible I want to do it right. Stay tuned to see what I will melt next week with this crucible.

Disclaimer: Please be aware that working with hot liquid metals is very dangerous! Do not try this at home if you do not exactly know what you do. I have done a lot of preparation and informed myself before I did my first pour.
If you do so, make sure to wear proper personal protection gear like a full face shield, a respirator, a dusk mask, fire retarding clothing or a leather apron, good protective and heat resistant gloves and leather boots. Make sure to work safe and use proper foundry tools.
Finally enjoy the hobby!
