Description

A complete nodule of baryte from the tertiary clays of Monte Paderno near Bologna.

These baryte concretions are known as 'Bolognese Spar', 'Bologna Stone' or 'Pietra fosforica di Bologna'. In 1602, Vincenzo Casciarolo, a cobbler by trade and dilettante alchemist, found that a stone from this locality, after calcination, emitted light in the dark without any external excitation source. The phenonenon discovered by Casciarolo was the first recorded observation of inorganic phosphorescence (cit. mindat).

From old Dr. Krantz stock, comes with antique typewriter label dated between the World Wars I and II.
