Difference btwn stove-top anodized aluminum and bakeware?

[chueh]

Why stove-top anodized cooking pans are all black (as if they have a coating. Even though the manufacturers claim no CFC, PTFE or PFOA)?

Why anodized bakeware always look just like aluminum color but not black (really look like no coating)?

Any anodized vessel, stovetop pan or bakeware, can be colored as part of the process.

Just a guess-- Bakeware often has a lighter color to moderate the browning process for a product that doesn't burn before it's completely baked. Stove top use most likely leans toward a faster browning response.

That makes sense as dark colors absorb heat faster than light colors. Anodizing is done by using electrical, or chemical compounds to create an aluminum oxide that is harder than aluminum, and isolates the aluminum from oxegen, and reactive chemicals. Anodizing is often used to protect aluminum parts from corrosion in salt water environments. It can be colored. Fly fishing guides are sometimes anodized in attractive colors such as black, gold, blue, etc.

The natural color of aluminum is silver-- see aluminum foil or the unpainted hull of an airliner.
