Question

In the past there were lots of containers that made of Al and Mg. People use them for cook them food without any care about them danger.

Answer 1

Not sure what Mg is but I do not cook tomato based food in my aluminum pots and pans. The acid has a reaction with it. I mostly use stainless steel cookware but I do not leave tomato products in it for long periods of time. I cook and then transfer it to another dish.
