Bleaching Protocol
Attain Balsa or Bass wood and cut wood samples in the transverse orientation with a band saw at approximately 5cm x 5cm x (0.33 - 0.50)cm. Sand the surfaces with 180p sandpaper on orbital sander to eliminate saw marks. Prepare or attain a 30% wt H2O2 bleaching solution and a 10% NaOH solution. Brush NaOH over desired bleaching area; subsequently, apply H2O2 in the same manner. Place wood samples under a UV-A (375 - 400nm) light for photocatalysis of the lignin depolymerization. Allow wood samples to rest under UV-A light until samples are visibly white (time will depend on the size of the wood sample and the area bleached).
