I has to be aluminum foil since there never has been such a thing as tin foil.

So, they've gotten to you too.

Sorry, you're wrong. Tinfoil was a precursor to aluminum foil. It was stiffer and harder to use and gave food a slight taste if tin so it was discontinued in favor of aluminum.

This is not a response that I expected. Maybe a response that one would get in Yahoo chat. I am a retired executive in the Aluminum industry,so have I have some knowledge of the metals industry. Just trying to point out that tin has never been made into foil.
