Furthermore, sand can function as an insulator and assist in reducing the temperature. So, add a little sand to the area beneath your fire pit for even more significant effects.

However, it would be best to wait at least a day before touching the slabs after grilling. It is because they may reach an extremely high temperature that can burn your hands.

Ember Or Fire-Resistant Mats

Ember mats offer proper heat shielding for grass surfaces and serve as a more portable option to heat shields. Manufacturers often construct them from heat-resistant materials like carbon fiber and volcanic rock. Some also claim extra insulating capabilities, such as air gaps built into their core design.
