Chatoyance was measured by the chatometry.com team using the PZC method. The statistics for this specific timber are hereby summarized to provide an evaluation of data robustness:
Number of sources for samples: 3
Number of individual trees analyzed: 6
Number of specimens: 10
Number of measurements: 36
Max PZC read (of all measurements): 19.0
Min PZC read (of all measurements): 12.1
Max PZC average on one log: 16.4
Min PZC average on one log: 13.3
PZC Average of all logs: 14.9

Species: agathis spp.
Family: Araucariaceae
Clade: Gymnospermae
Description: Agathis species (Kauri) are large, emergent conifers characterized by their distinctive broad, flat, leathery leaves and smooth, often peeling bark. They produce woody, globose cones that disintegrate at maturity.
