THE ELEMENTS
In the past, glass manufacturers added uranium to glass for color. Uranium has since become more strictly regulated, but the old uranium glass objects are still floating around. Because of the uranium content, these marbles glow bright green under ultraviolet light. ...

Musket Ball: Muskets were smoothbore muzzle-loading weapons, firing round lead balls or buck and ball ammunition, that were also designed to accept a bayonet. This style of musket was retired in the 19th century when rifled muskets (simply called rifles in modern terminology) became common...
WE LAUNCHED THIS PRODUCT ON KICKSTARTER AND IT WAS FUNDED OVER 200% If you compress any amount of mass, it becomes denser. If you compress it enough, it will become so dense that light can no longer escape it—this size...
With this future-proof table, blank boxes are arranged as placeholders for the predicted locations of undiscovered elements. When a new element is confirmed, write in its name, symbol, weight, and other properties it might have in the appropriate box. Includes...
Radium [Ra, 88] is a radioactive element, so it isn't something you come across everyday. But decades ago, it was painted on watch hands since it naturally glows in the dark. This practice was discontinued in the 1960s, and now these...
½ ounce (14 g) of pure zinc metal Zinc (Zn) is element 30, add this to your periodic table ¾” wide x 5/16” thick hexagon
Wafers are thin sliced semiconductors used to manufacture microelectronics and computer components. This sample is an 8" uncut silicon wafer with integrated circuits. Each wafer contains thousands of duplicate photo-lithographed circuits. Typically this wafer would have been cut up and the...
Lead is a chemical element with the symbol Pb (from the Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low...
One - 1 ounce, 99.9% pure copper bar Copper is what we call any atom containing exactly 29 protons. It is one of the most useful chemical elements to humanity. Copper was one of the first metals discovered and used...
Zirconium is an element with valuable properties. Don’t dismiss this element as “cheap” due to the commercial popularity of cubic zirconia (ZrO2). Pure Zr is a metal and one of the most heat and corrosion resistant elements. Due to these properties,...
This copper specimen is in its natural, dendritic formation, exactly how it looked when extracted from the Earth. Weight: 26g Copper is a chemical element with the symbol Cu (from Latin: cuprum) and an atomic number of 29. It is a...
