Magnesium 1" Metal Density Cube - 99.9% Pure Element for Chemistry - Periodic Table Design Educational Scientific Elemental Specimen

looks good, lightweight metal to compare with tungsten

Beautiful cubes from HeavenlyMetals.

I really enjoy my element blocks, makes for a great science and density project. The Magnesium and Zinc cubes from Heavenly Metals are the only ones I've found that actually have the correct elemental information on them, many others have wrong numbers or wrong temperatures. Laser etching is clean and legible. I wish the corners had a slight rounding to them (that's easy enough to fix with some high grit emory cloth) but you know you're getting all 1" of the element. my block weighed in at 29 grams so It is exceptionally close to the weight it supposed to be (28.51 grams). Enjoy.

For some reason I cannot give separate reviews for the two cubes I purchased.Mg - There are relatively small machining marks on the cube, unfortunately one is on the front and goes thru some of the print. Corners are sharp and could be dangerous, but I knew that going in, cleaning that up would be a more expensive cube. Overall - I am quite pleased, got this with a tungsten cube for comparison.W - This cube appears to be perfect, no machining marks. Very pleased, would recommend.It is 'trippy' to hold the Mg cube for some time, roll it around in the hands. Then set it down and pick up W - whoa!

We are happy to report that our new replacement Tungsten cube has the correct information printed on it. The seller was very gracious and responsive in replacing the original one that had been part of an accidentally misprinted batch. Thank you ‘Heavenly Metals’!

I really like this item. It actually contains the real element, and has information etched on the cube that is easy to read as if you are looking at a periodic table. I would buy this again.

I love the concept of these. The way that the mass of the block matches that of the element is a great idea. Interesting pieces to collect while also learning things.

Amazed at the feel of the weight this cube has. Heavier than expected. Arrived sooner than expected.
