Zinc was known to the Greeks and Romans as a constituent of the copper alloy, brass, but metallic zinc was not discovered until the 16th. century by Paracelcus. Zinc is a brittle metal which has a blue cast. It is readily accessible as it occurs in concentrated ores from which it is easily extracted (it has an abundance of 75 ppm in the earth's crust). Extraction is achieved by heating the oxide with carbon and distilling out the metal. Zinc tarnishes in air and reacts with acids and alkalis. Zinc is used widely throughout industry; for example, it is used as a galvanic coating on steel to prevent corrosion, and is used as a constituent of various alloy systems (e.g. with copper in brass), as well as in zinc-base alloys which can be used for diecasting (the other alloy constituents are aluminum, copper and magnesium). Pure zinc is used as an electrode in a Daniell cell and also in dry batteries. Zinc oxide is used as a stabiliser for certain grades of rubbers and plastics, as well as a non-toxic, white pigment used in paint manufacture. Zinc oxide also has astringent and soothing qualities and is used as a constituent of creams and ointments.

Technology meets passion and perfection

A piece of the universe - elements embedded in acrylic.

The innovation! Selected element samples in generous amount embedded in 50x50x50mm first-class crystal clear acrylic. Totally lightfast, high gloss polish. The text is embedded inside! Everything is hand crafted in the European Union!
Each acrylic block is a unique and individual piece!
EXTREMELY eye-catching!

In a world of mass production and high speed life, the chemical elements form an archaic antipole: They are a clearly defined, measurable and inmanipulable resource.

In our lab we only use materials of highest quality. We colaborate with renowned scientists, designers and artists to cope with the great responsibility.

Our element samples are used in many important and famous periodic table collections allover the world!

New! Complete acrylic cube set in illuminated display case

 

High purity Layered Black Phosphorus - Phosphorene electronic grade

Highest quality of commercially available black phosphorus crystals ideally suited for exfoliation.

 

Macro Image

 

High pure black Phosphorus crystals produced by gas phase transport - The highly shiny and very stable crystals have a bluish black metallic luster. Perfectly suitable for scotch tape method, liquid or any other type of exfoliation. These samples are perfecty suited for semiconductor experiments.

For detailed analysis data (XRD, Raman, TEM, TGA) please send a request.

Lanthanons ... These elements perplex us in our researches, baffle us in our speculations,
and haunt us in our very dreams. They stretch like an unknown sea before us - mocking,
mystifying and murmuring strange relevations and possibilities.


Sir William Crookes (February 16, 1887)
