Physical characteristics

Thickness: 1.0 $\pm$ 0.05 $mm$
Diameter: 30.0 $mm$
Volume: 700.0 $mm^3$
Surface roughness: low
Substrate material: aluminum anodized black
Substrate comments: diameter 30 mm, depth 1 mm
Comments: Mass of dry sample = 0.688g - used as martian analogue dust

Sample environment: Temperature

Temperature: 243.1 $\pm$ 0.5 $K$
Temperature max: 443.0 $K$
Time at Tmax: 600.0 $min$
Comments: Sample temperature error is mostly due to possible vertical temperature gradient in the sample. Temperature reading accuracy and stability is 0.1K
