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.

Other Information
Notes:
Slowly soluble in cold HCl (1:1) or HNO3 (1:1). Boiling H2SO4 (1:1) very slowly decomposes wherryite, leaving a white residue of PbSO4.
Heated in a closed tube, the mineral turns black without decrepitation and then melts.
Heated in a closed tube, the mineral turns black without decrepitation and then melts.
