Ultramarine

Until the beginning of the 19th century, Ultramarine Blue was a prized luxury product due to its extensive production process from the semi-precious stone lapis lazuli and obtained according to old recipes. Even today, the natural pigment ultramarine („azzurum ultramarinum“ = „blue from across the seas“) is as precious as gold.

Ultramarine is famous for its characteristic bright, deep blue color. From a physical point of view, ultramarine blue is positioned at the far short-wave end of the color spectrum, leaning towards the violet side of blue. The closer the color gets to the end of the visible spectrum, the darker it seems. Reproductions in books and photographs usually fail to convey the appearance and quality of ultramarine blue.

Since 1829, ultramarine pigments are also produced synthetically. It is a time-intensive process, during which kaolin, quartz, soda, Glauber’s salt, and sulfur are burnt together with carbon as reducing agent. The duration and temperature of the burning process determine the color nuance of the resulting ultramarine pigment. The chemical formula is Na8[Al6Si6O24]S4 and thus is identical with the one of natural ultramarine. Ultramarine can be understood as a complex sulpho-silicate. It is easily recognizable: If hydrochloric acid is poured on the mineral pigment, hydrogen sulfide gas will escape.

Around 1880, there were 24 factories producing artificial ultramarine pigments in Germany. In 1852, the new ultramarine factory Marienberg was founded in the Lauter valley in the Odenwald which existed until 1972. After the Blue Color factory Marienberg in the Odenwald was closed, some of its reference samples were set aside and stored in a garage. Decades later, when the garage was cleared out, the historic samples ended up at Kremer Pigmente.
