Comments on spectrum and activators:

Organic compound formed in burning pyritic shale or coal fires. It is not clear whether kratochvillite is the chemical fluorene (C₁₃H₁₀) or anthracene (C₁₄H₁₀).

Best localities for fluorescence (*):

• Freital near Dresden, Saxony, Germany;
• Kladno Mine, Libušin, Kladno, Central Bohemia Region, Bohemia, Czech Republic;
• Anna Mine, Alsdorf, Aachen, North Rhine-Westphalia, Germany;

(*)The data are not exhaustive and are limited to a few remarkable localities for fluorescence
