Our stones are made in top-of-the-line facilities and subjected to rigorous safety testing. Simply put, if it weren't safe, we wouldn't use it!

 

The production process locks some aluminum into the crystal lattice structure of the stone, but it is not pure aluminum like is found in aluminum cookware, and not materials leach out of the stone into the food.

The stone has been tested and is certified to be safe to use by the USDA, the EU, ROHS testing and German LFGB testing. These agencies have very tough certification procedures. RoHS, an international standard that ensures “Restriction of Harmful Substances,” is itself a difficult standard to meet.
