A few Black Locust (Robinia Pseudoacacia) and Black Cherry (Prunus Serotina) samples were subjected to chatoyance measurement straight after being cut with a reasonably sharp tablesaw, and then again after standard sanding up to 1500-grit. The charts below compare the results showing that good or bad chatoyance and brightness may generally be spotted just after a tablesaw cut – at least with these species.

Brightness is not significantly altered by sanding:
