Name
Pigment Bordezac - grains inf. 160µm, d=0.91
Type of layer
granular
Texture
pulverulent
Type of porosity
particulate
Density
0.91 $\pm$ 0.02 $g.cm^{-3}$
Comments
diameter / thichness is 14 mm / 3.5 mm in the Visible (0.508g / 0.936 g/cm3) @ SHADOWS and 18 mm / 4.5 mm for the NIR (1.070g / 0.914 g/cm3) @ SHINE. The density used is that of the NIR sample as the visible part of the spectrum is scaled on the NIR part.
