One of the greatest advantages of granite is that it can withstand extremely high temperatures and it is unlikely that your pans will become hot enough to leave a mark on your granite worktop surface. However, heat can and does affect the surface sealant that is often used to protect the granite’s high polish finish which is why we always recommend that you use a trivet underneath any hot items just to be on the safe side. In addition, granite is a natural stone and there is always a very remote possibility that a hot pan could open up a minute fissure that over time may develop into a crack. That’s why we recommend better play safe than sorry.
However, that being said, granite remains one of the hardest and most suitable natural stones to use in a kitchen environment and also in outdoor areas such as barbecue areas, outside kitchens, etc.
Recent studies that involved contaminating six different kitchen countertops with E. Coli bacteria and them washing and rinsing them with washing up soap and everyday cleaning practices found that granite is by far one of the most hygienic worktop materials around. Granite was shown to harbor significantly less E. Coli bacteria under regular cleaning practices than any of the other materials tested – including laminate, wood, tile, concrete and stainless steel.
