....or just don't use base metals anymore

Is it non-precious? Back when I worked in a lab that used Lite Cast B, there was always a layer of slag left in the crucible, I think it's supposed to stay there? It didn't stick, just lift it out and toss it.

I will use base metal

Oh, this STICK! and then after few castings its a 3mm thick layer of metal that CANT be removed so easy ....

I can remove some parts of it...but it sure does stick to the bottom and that is a problem.

Well they didnt told me in my supply store for LoliPot ...looks nice! hope it will work

Someone once told me that the flux would leave a glaze on the crucible that
may help - not sure if it will change property of casting if it gets on to alloy.
How old was that crucible?

When I had to use base metal for Maryland bridges, I used my old gold casting crucible that had a lot of buildup of flux and it worked great. Then buy a new gold crucible and everybody is happy

 

[VincentCeramics]

This one is old ...about 7 castings...

Hm...gold one i think ill go for..LoliPot

You pretty much always get some residue left when casting Non Precious, however, it usually comes out of the crucible quite easily (a little scrape should do it) I don't think flux is a good idea though.

Yea, We always De-Glaze our new crucibles with some flux and torch.
