I have stained Formica with hot blueberries. Perhaps there are some
other types that do better. I tested Silestone and was unable to stain
it.

All these surfaces will discolor if a hot pot is allowed to rest on them
for more than a very few seconds. The natural stone products may CRACK
due to thermal stress.

Discoloration from a hot pan is not a risk with Silestone & granite
although there may be certain granite sealers that may scorch. I was
able to leave a smoking hot cast iron skillet on a Silestone sample
with zero damage. I was also able to build a small fire with wood
matches on Silestone with zero damage as a result. Thermal shock is a
legimitate reason not to use non-metallic, heat resistant countertops
as if they are trivets.

I encourage people to get free samples from stores and test them for
themselves.

The MOST worry free surface is the laminates like Formica, however, they

I strongly disagree, but you're entitled to your opinion. I will give
Formica credit for being more scratch resistant than Corian.
