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.

Fluorescence of Sabinaite
Not fluorescent, but aggregates are sometimes coated in films of a gibbsite-type mineral that has an intense, white fluorescence under long-wave ultraviolet light.
Other Information
IR Spectrum:
An absence of absorption bands in the 3000-3900 and 900-1000 cm-l regions of confirms the absence of H2O and OH in the mineral.
Notes:
No reaction in dilute and concentrated (1:1) hydrochloric acid at room temperature, but is readily soluble with effervescence in warm HCl.
Health Risks:
No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.
