Name:
Named in honor of Alice and Frederick Kraissl, North Hackensack, New Jersey, avid collectors of Franklin, NJ, minerals, former officers of the Franklin-Ogdensburg Mineralogical Society and generous benefactors to the Franklin Mineral Museum. Alice Louise Plenty Kraissl [May 5, 1905 - September 16, 1986 River Edge, New Jersey, USA], earned a bachelors degree in engineering from Barnard College in 1925, and co-founded the family business, Kraissl Associates, with her husband. She was an avid micro-mounter as well and made many discoveries of Franklin-Ogdensburg minerals, including jarosewichite, flinkite, and several species still unnamed. Frederick Kraissl, Jr. [July 8, 1899 New York, New York, USA - November 30, 1986 River Edge, New jersey, USA] was the son of a Croatian immigrant. He earned his masters degree in chemical engineering at Columbia University, New York in 1922 and his PhD, also from Columbia, for his thesis on "The Mechanics of Colors in Gems and Minerals." He was a Practicing Engineer (PE), specializing in the manufacture of glass.

Based on recorded range of RI values above.
Interference Colours:
The colours simulate birefringence patterns seen in thin section under crossed polars. They do not take into account mineral colouration or opacity.
Michel-Levy Bar The default colours simulate the birefringence range for a 30 µm thin-section thickness. Adjust the slider to simulate a different thickness.
Grain Simulation You can rotate the grain simulation to show how this range might look as you rotated a sample under crossed polars.
