I tried ammonia but it didn't seem to have any effect. I remember reading that this is done commercially to stretch out the amount of marketable Black Walnut. Someone will doubtless jump in here with the relevant details, but if I recall correctly, it involved heating in water [?] to dissolve some of the colored substances from the heart and deposit same on the lighter sapwood... It's probably more complicated than that :-) I remember reading about walnut color in rec.woodworking about 10 years ago. Apparently some walnut trees never develop the wonderful brown colors - they're just a dingy gray all the way through. My understanding is that the heartwood darkens as the result of extractives in the soil as well as other factors. A fellow posting to the thread in r.w mentioned that walnut trees will put out 'suckers' - roots that spring up into trees. He said these always are gray and never get dark. Trees that grow from walnuts do. No idea if he was right or just blowing smoke. I do recall that lumberyards will steam or boil the wood - probably steam it - to get more uniform color. IIRC, Hoadly says the same thing in 'Understanding Wood'... ....Kevin -- Kevin Miller Juneau, Alaska http://www.alaska.net/~atftb In a recent poll, seven out of ten hard drives preferred Linux. |

Darkening cherry bowls
I have sold some walnut at a gallery, and got good prices ($400 to $800) for
pieces that featured a mixture of dark and light wood with a mirror like lacquer finish - in my case the light color came from rot, not immaturity, but it was quite spectacular (and took quite a bit of CA glue to get it hard enough to hold up so I could finish it) so, my suggestion is to not dye it dark "Bob Daun" wrote in message . ..

How do you know how a piece such as you describe and got good money for, will hold up 5, 10 years down the road? Do you ever worry that a piece will develop an ugly crack or something? |

I guess you don't really KNOW for sure, but these items are for display, not
use - so that helps - no one is putting them in the dishwasher, for example - and I was cutting from a fairly stable part of the wood - the soft punky stuff won't crack, if anything it would be the good hard 'real' wood.
