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! 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 |
Origin & History of Elements
Observations indicate that most stars are massive enough to enter a second round of nucleosynthesis. The depleted core - now rich in helium - contracts further, generating enough heat to start a thermonuclear reaction in a shell of hydrogen surrounding it, which fuses that hydrogen into helium. If the core's temperature gets hot enough, it undergoes a second wave of thermonuclear fusion itself, turning its helium into carbon and oxygen. The more massive the star, the more generations of nucleosynthesis it will experience. The most massive stars can have several layers of fusion going on at the same time, with the outermost converting hydrogen to helium, a shell beneath it turning helium into carbon and oxygen, a shell beneath that producing heavier elements, a shell beneath that creating even heavier elements, and so on down to a core in which iron is produced.
Once a star forms an iron core, its days are numbered. Up to that point, the nuclear fusion reactions produce energy, creating an outward pressure that counterbalances the inward pressure of gravity. But iron fusion uses up energy instead of producing it. So the outward pressure stops and even reverses, gravity takes over, and the star rapidly implodes until suddenly a vast number of neutrinos blast out of the core, blowing the rest of the star to bits in a supernova explosion that may be as bright as an entire galaxy. |

|
Since this happens only to very massive stars that have undergone a full range of stellar evolution, the explosion releases a wide variety of new elements into the interstellar medium (ISM), which may ultimately incorporate them into new stars and continue the nucleosynthesis process. |

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)
