Not necessarily.
Morta (bog oak) gets its color from the presence of iron in the water supply.
The iron reacts with the tannins in the oak's wood fibers (e.g. artificially antiqueing a cedar fence with an iron sulfate wash) turning them brownish/black.
Age both hardens and leaches out the wood's natural chemicals. This makes it less attractive to bacteria and fungal attack (aka: rot)
Without carbon dating the approximate age is unknown. I've got 6k year old brown morta turning blanks.
For woodworkers, brown morta is more difficult to locate compared to dark gray.
I find the brown more appealing.
That is very informative Brad, thanks. I was under the impression that the darker the morta, the older it is. I think I read this somewhere...
