Some of the recent reviews state that these are in fact nickel lined. Is this true, and are they solid copper?

not solid copper, nickel lined, I was rather disappointed finding that out b/c the description they provide is a blatant lie

I tested mine with a straight iron to be sure they were real. They melted. So I would say no.

They are brushed nickel over the entire surface. Brushed nickel is a sort of striated, rough finish.

I believe they are, but I have returned this product due to small pits and rust just after one use, also its very thin walled and base.

No, just pure copper.....but if you're buying it for Ayurvedic purposes, that's all you want. Once you get used to the pureness of a noncontaminatory metal, anything with a liner is just nasty ;-)....but that's just my two coppers.

No. It's in the product description. They are copper clad aluminum. "High-strand count (0.254mm x 26 strands) copper clad aluminum conductors"

I believe they are. I cut some off and looked very carefully. It does look like copper.

As far as I can tell, they are stainless. I don't recall exactly when I bought them, but I would guess at least several years ago, and they have not shown any surface corrosion to date. As to the magnetic properties others have mentioned, generally speaking Austenitic stainless (304, 316, etc.) are not magnetic, but the Ferritic 400 series generally are.

I thought based on this picture that I was going to get the more brownish ones pictured here. But the ones that came were a true satin nickel finish. Definitely more silver unlike what is pictured.

Not sure, but I believe they are solid copper - one of the threaded holes stripped out too easy to be steel.

It is solid copper. We have used them a couple of times and they look great. We handwash them and will continue to do so. I'm very pleased with this product!

they are not solid copper. if they were solid copper they would be worth more as scrap than what they are selling for. they are also very heavy as is, 20ft of #2 copper would make them unwieldily.

I don't believe they are. They are stainless steel and no where did I see that they were full tang

Yes, these are real. It has a sticker labeling it's voltage, mAh, and 18650 size but that can be removed. The positive lead is flush, as well as the negative. No weird discoloration of the wrap and no seam. These are real. At least the ones I got were real.

Don't know. Didn't put them in the oven but I would assume they are,they're copper. I wouldn't advise picking them up right away with your bare hands.

They are copper alloy. None of these cups are 100% pure copper...that would be super expensive. Color change is common with any copper product.

I couldn't guarantee they are pure Pb, but they ARE soft (If I squeeze one hard, the skirt flattens, seem softer than 60/40 solder).
