Post subject:  fumed white oak

I think I want to use a set of white oak for my next project. I've seen mention of 'fuming' the oak in an ammonia atmosphere in order to darken it. Sounds like I might want to do that. Now what? I'd love some comments, advice, information, opinions....

Thanks!

It does work. Or you can dilute the ammonia with water and use a rag. Keep in mind, this is mostly a technique furniture makers have employed. I've never done it, just read about it in Fine Woodworking.

Oops. I see my comments from 14 months ago in that thread, too. I dead forgot I'd asked about this before. Thanks!

I'm working on a white oak body that I fumed. Made a tent w/pvc pipe frame and clear poly over. Got some 28% ammonia @ Amazon (careful of the fumes!!) and left it in about a week. Came out a nice honey brown. Now if I could get the AquaCoat to fill the pores (I'm up to 10 coats so far) I'd get on to the finish.....

Yup, I haven't got the hang of it either. idunno

I completed one a couple months back, too. Put the body in a clear plastic dry cleaning bag with some household ammonia for about 6 hours and checked it. Decided a few days later to do more so I left it in overnight. Did the trick and as mentioned a nice honey brown color. I used a couple coats of System 3 epoxy which worked nicely.

I haven’t fumed a guitar body yet, but I filled the pores in one recently that had QS white oak back and sides. The pore filling was a real challenge. I used Silver Tip. It eventually worked great, but it took a LOT of coats.

I haven't "fumed" one yet, but might try that in the future. I did "ebonize" one using vinegar and old rusty nails, steel wool, etc.
