• 70% denser than lead

MagnesiumSphere / Cube

• 1/10 the density of our Tungsten sample
• The lightest metal used for engineering
• only 2/3 the density of Aluminum
• Highly flammable when powdered or cut into thin strips
• Extremely important to our health, especially our bones
• Sample density: 1.80 g/cc
• Surface finish: brushed

• The strongest metallic element
• Shockingly rigid and lightweight
• Non-magnetic
• Resistant to many acids
• Extremely high melting point (3034 degrees F)
• Sample density: 4.51 g/cc
• Surface finish: cube (brushed); sphere (mirror polished)

• It’s Oligodynamic, which means it naturally kills germs on contact.
• We each have about 2mg of copper in our body, without which we could not survive.
• It’s dense - between lead and steel in density
• Along with gold, the only non-greyish pure metal
• Takes on its own unique hue over time and can be “reset” to brilliancy with baking soda and water (or salt and vinegar).
• Sample density: 8.96 g/cc
• Surface finish: cube (brushed); sphere (mirror polished)

• A kilogram of silicon-28 goes for about $1.5 million, so we needed a more reasonable alternative.
• Our sphere would be off-the-shelf crystalline silicon used in making computer processor chips (thank you computer industry!).
• Our sphere would need to be 0.39% smaller, which is 93.38 mm.
• Since the CNC lathe we wanted to use in the final process is accurate to about 0.01 mm, this is a significant difference in the input code.
• Sample purity: 99.9999999%
• Surface finish: mirror polished
