Do some copper pots have a "coating "of aluminum? Has anyone heard of them being dangerous to use? Mine have a silver or tin colored layer. The frying pan looks like solid copper. Is there a good, natural cleaner?
Is the copper worn down and you're seeing the tin underneath? I'm not sure, but think they all have a base layer of another metal, usually tin. Good copper pots are very pricey, but it's the best conducter of heat. Old timey method of cleaning copper is catsup, it removes the oxidation. Ronna
