Another processing engineer suggests that a porcelain crucible be used for the water quench from 500° C. Would you endorse this plan? Again, explain.

Solution

Yes, I will endorse his suggestion.
Reasons:
Porcelain containers can withstand abrupt temperature changes without the problem of cracking.
A typical porcelain container can withstand temeratures upto 1150⁰C or even upto 1300⁰C.

So, that makes a porcelain crucible suitable for a water quench from 500⁰C.
