New Kickstarter is Live! - PT Cubes

How would you like to have elements from the Periodic Table on your desk that you can feel and touch? Well, now you can! Order the PT Cubes Today! For one low price, you can order a set of 4 cubes.

Are you a Teacher, an Engineer, or just someone who likes cool desk toys? Well, now you can have your very own elements from the periodic table at an arm’s reach with PT Cubes.

When these are on your desk, you can look, touch, and hold them.

If you are a teacher, you are bound to talk about these elements. How impressed would your students be if you handled them a block of a real element?

If you are an engineer, like myself, you are always thinking outside the box about the next big thing. With these blocks, you could play with them, or compare the materials for your next project.

Even if you aren’t a teacher or an engineer, you can place these on your desk or on a table at home for great conversation pieces. Impress your guests with elements that they never heard of!

What elements will you get if you order?

For the lower level (Starting at just $38 USD), you will get 4 PT Cubes with 1 stand. The elements you will receive are Aluminum (AL), Zinc (Zn), Iron (Fe), and Chromium (Cr).

Aluminium is a relatively soft, durable, lightweight, ductile, and malleable metal with appearance ranging from silvery to dull gray, depending on the surface roughness. It is nonmagnetic and does not easily ignite. A fresh film of aluminium serves as a good reflector (approximately 92%) of visible light and an excellent reflector. The yield strength of pure aluminium is 7–11 MPa, while aluminium alloys have yield strengths ranging from 200 MPa to 600 MPa. Aluminium has about one-third the density and stiffness of steel. It is easily machined, cast, drawn and extruded.

Zinc is a bluish-white, lustrous, diamagnetic metal, though most common commercial grades of the metal have a dull finish. It is somewhat less dense than iron. The metal is hard and brittle at most temperatures but becomes malleable between 100 and 150 °C. Above 210 °C, the metal becomes brittle again and can be pulverized by beating. Zinc is a fair conductor of electricity. For a metal, zinc has relatively low melting (419.5 °C) and boiling points (907 °C). Many alloys contain zinc, including brass.

Iron metal has been used since ancient times. Pure iron is relatively soft, but is unobtainable by smelting because it is significantly hardened and strengthened by impurities, in particular carbon, from the smelting process. Crude iron metal is produced in blast furnaces.

Chromium is remarkable for its magnetic properties: it is the only elemental solid which shows antiferromagnetic ordering at room temperature (and below). Above 38 °C, it changes to paramagnetic.

For the upper level (starting at $110 USD), you will get the 4 above + 1 Stand, and the following 4 PT Cubes with another stand. The elements you will get extra include Titanium (Ti), Nickel (Ni), Copper (Cu), and Zirconium (Zr).

Titanium, as a metal, is recognized for its high strength-to-weight ratio. It is a strong metal with low density that is quite ductile (especially in an oxygen-free environment), lustrous, and metallic-white in color. The relatively high melting point (more than 1,650 °C or 3,000 °F) makes it useful as a refractory metal. It is paramagnetic and has fairly low electrical and thermal conductivity.

Nickel is a silvery-white metal with a slight golden tinge that takes a high polish. It is one of only four elements that are magnetic at or near room temperature, the others being iron, cobalt and gadolinium. Its Curie temperature is 355 °C (671 °F), meaning that bulk nickel is non-magnetic above this temperature.

Copper is one of a few metallic elements with a natural color other than gray or silver. Pure copper is orange-red and acquires a reddish tarnish when exposed to air. The characteristic color of copper results from the electronic transitions between the filled 3d and half-empty 4s atomic shells – the energy difference between these shells corresponds to orange light.

Zirconium is a lustrous, grayish-white, soft, ductile and malleable metal that is solid at room temperature, though it is hard and brittle at lesser purities. In powder form, zirconium is highly flammable, but the solid form is much less prone to ignition. Zirconium is highly resistant to corrosion by alkalis, acids, salt water and other agents.

About the blocks are base:

The base will have 4 cutouts to display; it is made out of Aluminum and will be Black Anodized. This is made in the U.S.A.

All blocks will be made overseas; all will be polished and be labeled with a laser similar to the Aluminum block. Due to high costs, we were only able to obtain some samples of Aluminum, but the other blocks that are smaller are just examples of the final product. Each block is a 1” (25.4 mm) Cube. All metals will contacts at least 90% of the original metal.

We have delivered fully and on time for our previous Kickstarter projects and we plan on doing the same for this one!
