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

The name catgut is confusing. There are two explanations for the mix up.

Catgut is an abbreviation of the word cattle gut. Gut strings are made from sheep or goat intestines, in the past even from horse, mule or donkey intestines.

Otherwise it could be from the word kitgut or kitstring. Kit meant fiddle, not kitten.

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.
