thermal issues w/ solid countertops

[turbodog]

FYI,

For those that have solid surface countertops... in particular, the composite types (silestone/quartz/etc)... they are not as thermally resistant as you might think.

They appear to be fine for reasonable periods for normal hot/cold (oven/freezer) items.

To note, extremes of temp or TIME will be a problem.

I was using some dry ice a few years ago, and the counter popped. Have a crack now that's viewable at the right angle/lighting.

Couple of weeks ago, I was cooking using a sous vide. Only 140F, but lasted for 24 hours. Had been cooking in the same spot this way for years. Now I have a nice new crack.

Good to know. We have quartz, and were told to not use vinegar on it but alcohol is ok. We use silicone trivet/pot holders to also lessen the scratching and etching from titanium. The Ti clip on a Spyderco makes marks on the edge when I lean against the countertop sideways.

I've not seen problems with vinegar, alcohol (isopropanol or ethanol), acetone. or anything. The dry ice cracked it after 30 mins of exposure in a 6" dia pot. The sous vide... guess it cracked after years of use in the same spot for hours/days on end.
