Box Elder fade test *PIC* ()

Found the handout I had made on red box elder. The study on the cause of the red coloration is at

http://www.plantmanagementnetwork.org/pub/php/research/redstain/

(which is still on the Internet on 11/11/2018) and the mention of a chemical analysis of the red color was in a forum on turned wooden pens (did not note the forum name or the citation) but the chemistry professor neighbor found the red color to be a phenol compound that would be modified to a brown color by the energy in sunlight. It would seem likely that the energy in artificial light would have the same effect, dependent on the relative amount of energy in sunlight and artificial light.
