Description

Old test glass with cork stopper containing about 50 idiomorphic arsenopyrite crystals with dull metallic luster and mostly rhombic shape.

From old Dr. Krantz stock, comes with antique J. Sasamoto label. Jiro Sasamoto was a famous Japanese mineralogist in the 1800's. T. Wada "Minerals of Japan" refers to Dr. Krantz aquiring a number of Japanese minerals from him. Unfortunately there is no more information available about this scientist, not even at the Krantz company itself. These old labels are very rare; Japan was a closed country at that time and there were not nearly as many mineralogical collections as in Europe.

Size is given for the test glass, weight includes test glass.
