Copper Knowledge

This is the reference shelf: how copper conducts heat, why it reacts with acidic food, what tin and stainless linings each do well, and how copper stacks up against stainless, cast iron, and clad aluminum. Understand the material and every buying decision gets easier. We stick to established metallurgy and food-safety consensus — unlined copper is reactive and not safe for cooking acidic foods, tin linings wear and eventually need re-tinning, and stainless linings trade a little responsiveness for durability. Where the evidence is mixed or the tradition is just tradition, we say so.
