Among the chemists who have attempted to explain fetid fluorite have been Friedrich Wöhler 1800-1882 and Justus von Liebig 1803-1873 . Indeed Wöhler proposed that F 2 was responsible for the smell in a letter to Liebig in 1861.

Fluorite or fluorspar is one of the commercially significant minerals which consists of calcium and fluorine or CaF2. Thus it is a commercially important source of fluorine. It possesses glassy luster and occurs in variety of attractive colors due to presence of trace amount of other elements substituting calcium.

The centrepiece of the electrolysis part of the cell is a 1cm 2 working electrode made from graphite which is held just above the plastic substrate by 0.2mm-thick spacers creating a thin chamber under the electrode. The capillary then runs directly below this chamber with a small hole in the bottom of the chamber providing a way for any

The reason is the presence of purple fluorite CaF 2 in a mixture with lead white charcoal black and earth pigments. The investigation of the micro-samples proved the use of fluorite too see Fig. 3. Purple fluorite has also been identified in the oeuvre of the Master of the Litoměřice Altarpiece and his workshop Chlumská et al. 2010 .
