Yes, granite worktops are heat resistant. They can withstand high temperatures without being damaged or discoloured. However, it comes with limits.
A granite worktop is a type of countertop made from natural stone (granite) that is widely used in kitchens and bathrooms. However, pure granite can be quite brittle and prone to cracking or breaking, especially if subjected to heavy use or impact. To make granite worktops more durable and suitable for use in homes and businesses, a resin or polymer binder is added to the surface.
This binder acts like glue, holding the granite pieces together and reinforcing the surface. The binder also helps to fill in any cracks, chips or imperfections in the granite, making the worktop smoother and more even. This process of adding a binder to granite is called “engineered granite”. The result is a granite worktop that is strong, stable, and less prone to damage than pure granite.
Additionally, while granite is naturally heat-resistant, different types and grades of granite can have varying levels of heat resistance. It is always best to err on the side of caution and use trivets or heat pads to protect both the granite surface and the resin or binder.
