I’m working on a new project with quarter sawn white oak and I need to fume it. I have read all the instructions and safety precautions so now its time to test a few pieces. One problem….can’t locate any aqua ammonia or ammonia hydroxide. Anyone know I can purchase it or can I use household ammonia? Need a little direction here…..

Household ammonia will work just fine.
Work with some scrap pieces first to establish the time.

Kevin Rodel Wrote in a Finewoodworker article:

This industrial-strength ammonia
is used in machines that reproduce
blueprints and surveys, so you can usually
find it at business-supply, blueprint-supply
or surveyor-supply stores (look in the yellow
pages for a supplier).

If you can get a hold of the article I’m sure it would be helpful too.

Got it….picked up some household ammonia today so I’ll test a couple of pieces tonight and see what happens.

Thanks

Household ammonia, if it is “lemon-freshened”, is sure to disappoint. The citric acid will have neutralized some or most of the ammonia into a neutral salt. Try a janitorial service if you want some floor-stripping power ammonia. As has been mentioned above, ammonia is bad news if handled improperly. I was patinating some copper, and made the mistake of leaning over the tank. Even with a small amount, I was nearly overwhelmed. Be careful with it! It damages you by dehydration. If you walked into a room with an ammonia atmosphere, the responders will wait until the fog clears to get your shriveled, prune-like corpse. Seriously.

Picked up plain household ammonia and fumed the oak. It took about 3 hours to do what full strenght would do in 1 hour but the results are the same, a very mello gray tint. Years ago I did some refrigeration work for and ice plant using ammonia as refrigerant so I’m well aware of ammonia’s nasty side. This household stuff is nothing compared to that. But I was faster then, now I’m slower like the HH ammonia so we work well togehter. Ha!.....................Thanks to you all for you helpful advice.
Blessing to all.
