Okay, gang: While I agree that not labeling samples at once is a bit odd, and also a bit rude, it only takes a second to identify them. See attached image/video for reference. (TLDW: Iron is magnetic. Lead bends if you look at it with your eyes. Aluminum is by far the lightest and weighs about half that of zinc.) I bought this because I was looking for graphite anodes. for an electrolytic bath to remove rust (it's happily simmering now, so graphite isn't on the list, but again: if you're having trouble with that... chemistry might not be in your best interest yet <3). Others cover most home electroplating applications (it's the same process as rust removal, just the other way around), so what's the price? Absolutely outstanding. I bought two sets. Yes, one of my Graphite broke about halfway, but since my first action after seeing the same thing was to break the other in half as well (so I had an anode for each cardinal surrounding the artifact to be deoxidized ), that didn't help. This worries me too much. Aside from a dubious business decision not to label samples, which I found to be a 20 second job with a quality improvement marker, I would recommend this purchase to anyone supplying for electrolysis or dealing with electroplating. Note that the samples are about half a dollar and about 7-10 ems, so you won't be able to bronze a moose's head (or whatever they do). but if you want to make minor repairs or add some shine to a gear, you're good to go. I can only recommend this to a friend. Hope that helps!
