Ceramic for ingot molds?

[DanOH]

My wife has a collection of small corningware type bowls leftover from her bird breeding days. They are just the right size for ingots.
Any ideas on whether they could handle molten lead?
Thought I'd ask yall before I ask her....

Brave, ain't you????

[HATCH]

I would say NO.
You would crack them in a skinning minute
the temp change thing would do them in.

Yeah, I wouldn't trust them. We use ceramic coatings for high temperature equipment but that's a thin layer applied to a metal component.

The one quickest thing to ruin the ceramic face on the mechanical seals on our centrifugal pumps is thermal shock. Probably wouldn't try it if it were me.

[DanOH]

Yeah I'm not brave enough to try it.
Guess I was thinking along the lines of the ceramic tiles on the space shuttle heat shield.

I am old enough to remember the Corning ware commercials. Glowing red hot bowl dropped into ice water with no damage. That being said I do not know about getting the ingots out of the bowls.

They won't take the sudden temp change and explode. My wife has a new Corning wear bowl I bought her. And Boolit lube doesn't get nearly as hot as lead. That's all I'm saying about that.

I'd heat them up to drive off water, if I did have the courage to try pouring molten Lead into them (which I don't).
