Na12Mg7(SO4)13 · 15H2O
Colour:
Colourless, reddish-yellow; colourless in transmitted light
Lustre:
Vitreous
Hardness:
2½ - 3
Specific Gravity:
2.374 - 2.423

Name:
Named in 1846 by Wilhelm Karl von Haidinger in honor of Alexander Löwe (24 December 1808, St. Petersburg, Russia - 29 March 1895, Vienna, Austria-Hungary), chemist and Chief Assayer at the Mint, Vienna, Austria and later director of the Porcelain Works. He was the first to efficiently extract tellurium form Nagyág ores. He also described gersdorffite. The mineral name also appears as loeweite in English texts, but the löweite spelling was confirmed in 2008.
