I am building a fireplace surround out of tile and african mahogany.
The mahogany boards are of varing degrees of aging and therefore of
varying degrees of color. I need to age them to a consistant color. I
know they will eventually turn color but in the meantime I have to live
with some light tan areas and some deep brown. Any suggestions? Leo
Yep...put them in the sun light...of course that will cause
other problems... You will need to tint,dye or stain that
wood to get a constant color(which is what factories do).
Thanks, I knew you would say that. Probably by the time I get done
planing they will all be about the same hue. I have used this stuff
before and like the ribbon grain but sometimes the color is a problem.
Mahogany can be darkened with a dilute lye solution. Experiment with
strength, but just a few percent worked well for me. The effect is
instantaneous. Some will say you need to neutralize the lye with a
weak acid, but I haven't found this necessary. I believe exposure to
the air for a time will do it.
I've never neutralized the lye, and haven't seen problems with finishes
(the main concern, I think). Lye is a strong base, and I wouldn't be
surprised if it would mess up the chemistry of a finish material. Lye
loses strength when exposed, though. I suspect that the NaOH reacts
slowly with atmospheric CO2, leaving sodium carbonate--a much more
