Terrific!
I am using for a rather “strange” application. Read in a book by Mellie Uyldert that soldiers that suffered asthma at home did not have asthma at the front. The improvement was caused by the wearing of zinc identity tags against their chest/windpipe. Zinc was continuously absorbed through the pores. The author suggests wearing a piece of zinc against the the skin by the windpipe. These pieces are just the right size. Taped it there last night and have not had to use my inhaler yet today. Weird…I know…but worth a try. He mentions that the breathing difficulties have something to do with low alkali reserves in the blood with an acidified organism unable to purify itself due to breathing problems. The name of the book is “Metal Magic, The Esoteric Properties and Uses of Metals.” It’s old but VERY interesting. Bought it “used”.

Great for school density experiments
I bought these for middle-school science club for a density project. I am measuring density at about 7.6 g/cm3 using the Archimedes method, and the official zinc density is 7.13. I am using a 50mL graduated cylinder to measure the volume and a basic calibrated digital scale, so there is room for error there for sure. But I do wonder about the 99.99 pure statement. But for my purposes they work fine.

seems legit
I received 8 little hexagons of zinc. Total weight 100.90 grams. I don’t have a spectrometer to verify the 4N purity claim, but a water displacement test seems to agree with them being pure zinc. (~14cc’s displaced, which is 7.14g/cm3 within the accuracy of my measuring cup and syringe :P)Notably but not probably relevant, the hexagons are much duller than in the product picture. They are a drab gunmetal grey.

Not even close to the size pictured.
In the picture that shows according to the tape measure there an inch of crossed the ones I got were only a half an inch across! Wonât work for what I needâ¦Why canât people just be freaking honest?
