This is NOT a paperweight, magnesium is not incredibly dense and id imagine this is mostly used for display purposes, but it can be grinded down for magnesium shavings to start a fire, etc. Very cool for any chemist to have Review: Must have for your element block collection. - 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. ## Features - Pure Magnesium Cube: Made from 99.9% pure magnesium, a lightweight and vital element. - Incredible Accuracy: Crafted with a dimensional tolerance of +/- 0.1 mm for the utmost precision. - Feather-Light Feel: Weighing approximately 0.13 ounces (3.6 grams), this 0.5-inch cube is incredibly light, highlighting magnesium's low density. - Lustrous Element: With its silvery-white appearance, the cube demonstrates magnesium's aesthetic and physical properties in a tangible form. - Versatile Gifting: An excellent gift for science lovers, educators, and collectors, featuring essential details like atomic number, atomic symbol, melting point, atomic weight, density, and purity on the cube. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CRSV931P | | Best Sellers Rank | #95,186 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #127 in Science Classroom Specimens | | Brand | Heavenly Metals | | Brand Name | Heavenly Metals | | Color | silver or white | | Customer Reviews | 4.7 out of 5 stars 30 Reviews | | Grade Rating | Commercial | | Item Diameter | 0.5 Inches | | Item Dimensions | 0.5 x 0.5 x 0.5 inches | | Item Form | Solid | | Item Shape | Cube | | Item Thickness | 0.5 Inches | | Item Weight | 3.6 Grams | | Item dimensions L x W x H | 0.5 x 0.5 x 0.5 inches | | Manufacturer | Heavenly Metals | | Material | Magnesium | | Number of Items | 1 | | Part Number | Mg-Cube-0.5 | | Shape | Cube | | Specification Met | Yes | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Heavenly Metals - **Color:** Black - **Item dimensions L x W x H:** 0.5 x 0.5 x 0.5 inches - **Material:** Carbon - **Shape:** Cube ## Images ![Magnesium 0.5" Metal Density Cube - 99.9% Pure Element for Chemistry - Periodic Table Design Educational Scientific Elemental Specimen - Image 1](https://m.media-amazon.com/images/I/51flbj7lyeL.jpg) ![Magnesium 0.5" Metal Density Cube - 99.9% Pure Element for Chemistry - Periodic Table Design Educational Scientific Elemental Specimen - Image 2](https://m.media-amazon.com/images/I/6162vvm7eIL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ NOT a paperweight - for display / grinding / etc *by T***S on February 7, 2025* Really cool product, i wasn’t expecting the etched engraving to actually be there but it is!
