No but I've read up on it a bit. It was common during the Mission Furniture period. H. H. Windsor wrote a series of articles that appeared in Popular Mechanics back about 100 years ago. It was compiled into a book eventually. Fuming was part of the look and one or more of the articles describes the process in detail. The copyrights have expired long ago and I've seen free downloads of the book on the net although the book is also available, usually at a reasonable price. It's a reasonably good investment if you like Mission furniture as the book is a series of designs which you can build or use for inspiration.
All of the designs Windsor intended to be made from white oak which is high in tannin which is what the ammonia vapors react with. Basically you just build a tent around the piece and leave a saucer of ammonia inside and wait. It takes days for the process to work. I have no idea what the strength of ammonia Windsor had available to him at the time but I would use the strongest that you can find.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
