Now, we’re working to make our metal cubes more accessible and affordable than ever before.

Starting March 22nd-April 5th, take 20% off the already low price for our beautifully engraved density cubes, letting you hold the building blocks of the universe right in your hand! Check out some examples below, and be sure to visit our online store for a complete list of what’s available in metal cubes, mirror cubes, rounds, refined crystalline samples, and of course our signature Lucite acrylic sample cubes as well!

Aluminum

Look around your home. Chances are you use aluminum every day: the rims on your car, the “tin” foil you use to cook and cover leftovers, light switches, screws, your computer, your TV—all made from aluminum! Luciteria Science makes this humble, commonplace material exciting and unique to handle with metal cubes of the highest possible purity.

Arsenic

Maybe you want something a bit more—Gothic? Many people don’t realize arsenic is a metalloid. Our arsenic cubes are great educational tools that will inspire conversation, imagination and make a wonderful accent piece for your office or home. Sorry, Old Lace not included!*

Calcium

When most people think of calcium, they probably think of healthy bones and teeth. Luciteria Science’s calcium cubes show off this elemental metal to its best possible advantage, letting you see and in its purest and most refined state.

Copper

If there’s an element more ubiquitous than aluminum, it’s almost certainly copper. Copper lies at the heart of technology, electrical power, and even American currency in the form of the humble penny. These striking cubes are engraved with copper’s periodic information, and also make amazing accent pieces! Available in both a standard finish and in a mirrored polished finish.

Gadolinium

Gadolinium is one of the exotics known to chemistry majors as the lanthanides. It’s magnetic and often used in old-style television picture tubes, microwave ovens, and as a contrast dye in medicine (used in MRI scans). As a cube, gadolinium makes a surprisingly beautiful and hefty educational and discussion piece. Stump your friends by testing their knowledge about this lightly regarded element and all the heavy lifting it does for us! Available in both a standard finish and in a mirrored polished finish.

Indium

For a metal, indium is very delicate. So delicate, in fact, that you can easily shear through it with tin snips—or a big knife and enough leverage. Because these cubes are so easy to damage, they are shipped in cotton and we strongly recommend they be handled only with your hands. They make a wonderful gift sample for the sensitive soul or the hardcore element collector in your life!

Lead

Lead’s properties are very well known: soft, heavy and dark gray. It’s one thing to know this, and a very different proposition to actually see and hold a pure sample of it in your hand. A fun way to explore lead’s properties and teach kids about different metals. Just don’t let anyone try to make an afternoon snack of it!*

Praseodymium

Magnets, cigarette flints, and even aircraft engines: praseodymium appears in a lot more places than you might expect, although its complicated name and affinity for oxygen makes it one of the lesser-known metals. These cubes have to be shipped in glass vacuum-sealed ampoules to preserve their appearance because in the presence of oxygen they’ll quickly crumble into a whitish powder rather than the handsome black finish you see on our site. A unique addition to any element collection!

Tungsten

Denser than lead, harder than titanium, less reactive than nearly any other metal, and with a higher melting and boiling point than any other metal, tungsten is the unsung king of the metallic elements. Now you can hold this element in the palm of your hands and feel for yourself how much heavier it is than even lead. The spark-erosion process used to create the finish on our tungsten cubes offers the highest possible beauty, form, and function! Available in both a standard finish and in a mirrored polished finish.

Yttrium

Highly reactive to oxygen and oxidizing even more readily in water, there’s not much call for yttrium in commercial processes. This exotic metal is difficult to find and even tougher to refine and shape into reference cubes without damaging the finish. However, its sheer rarity makes it a coveted item for many element collectors and private laboratories, as well as a great gift for someone truly unique and one-of-a-kind in your life! Available in both a standard finish and in a mirrored polished finish.

This sale only runs until April 5th, and applies to all in-stock Luciteria Science density cubes.
