Can I put hot pots on the countertops?
As with almost all types of countertop surfaces, it is generally best to use trivets. Most often it is the sealer that is heat sensitive. And some sealers can tolerate much more or much less heat than others. Additionally, concrete can microcrack if exposed to high heat, and some types of sealer are not elastic enough to absorb these microcracks. The surface will appear crazed, especially when it is wet. However, again this depends on the sealer, and you should ask your fabricator how his sealer will perform. For comparison, some granite will exhibit quartz “pops”, where heat causes the quartz grains to expand and pop out. And solid surface materials can crack because of their generally poor thermal expansion characteristics.
