Hi,

I've a small oven rated 200C. I wonder what sort of issues
would be involved in increasing this to ~300C? Obviously,
putting more power into the unit, etc.

But, I worry about things like the capabilities of the
insulation, materials within the oven, etc.

Though I find it hard to believe that I can easily hit 260C+
with a countertop convection oven without *it* melting or
otherwise self-destructing and this industrial/laboratory oven
wouldn't be capable of likewise (?)
