All measurements rounded up to the next whole decimal.

Resulted in a stable, gloss, brown with green hue. More interesting =
around thinner edges, with bluer cast. Not bold, not black, but not =
entirely ugly.
Has a nice smooth surface that sparkles like a tessha brown.

Best regards,
Alisa in Denmark
