One hundred years ago, Max von Laue received the Nobel Prize for proving that X-rays are diffracted by crystals. This discovery was simultaneously the birth of modern crystallography which has used X-rays for the non-destructive analysis of the structure of solid matter ever since then. On the occasion of this anniversary, the UNO proclaimed 2014 the International Year of Crystallography.
Crystallography plays a crucial role in the development of almost all new materials for everyday products. The fields of application of this branch of science are extremely diverse and also affect developments in agriculture, aerospace, automotive and aircraft construction, electronics, cosmetics and pharmacy. However, cristallographers not only study the structure of materials, they also use this knowledge to change structure and thus give materials new properties.
Through the "Metamorphosis Sequence 1" (value: CHF 1.00) and "Metamorphosis Sequence 2" (value: CHF 2.00) stamps, the Philately Liechtenstein is drawing attention to this influential field of science. Set out in a row, the stamps show how a crystal grows over thousands of years. With the aid of a free app (SEPAC Stamps) the postage stamps can be scanned and the metamorphosis of the crystal then observed by means of a video animation by the artist Bianca Violet. The stamps are issued on a 16-stamp sheet and were produced in a multi-stage stamping process and finished with UV gloss coating.
