furnace and crucible doubts

[paolo]

Hi all,

I have a question for all those that use a furnace to melt their own silver.

Once the furnace is at 1100 degrees, and the crucible we are using is been operating already quite long, is it possible to insert a fresh crucible inside the furnace immediately at 1100 degrees? or it does need some slow heating?

Does the crucible need borax inside it?

Thanks to all who will share their knowledge!

The crucible need to be preheated slowly, you cannot insert it in the furnace when the crucible is cold and the furnace is already at melting temperature
