    Oxidises and creates a hard layer so the aluminium doesn’t leach or react with acids.

      Yes, they are modern aluminum, so no dangers. They just don’t work on induction.

          Explain.

          When exposed to atmospheric oxygen, pure metallic aluminum reacts almost immediately to form a dense, protective Aluminium oxide layer about 2 to 5 nanometers thick.

            They use electrolysis to make a 10 to 20 micron layer.
