Crystallized sulfur (Conil, Cádiz, Spain)

One of the biggest treasures of the museum are the samples of crystallised sulphur from Conil (Cádiz, Spain), some of big size and perfect crystallization, collected in 1791 by Francisco Javier Molina.
The Museum keeps more than 60 samples of crystallized sulphur. Some of them are really spectacular and were exhibited at the Universal Exhibition in Paris, 1867.
