   l got mine from argo graph process Ltd in toronto,416-749-4818.

   If you try some commercial print shops  they should be able to help you out.

   A word of caution,make sure you use protective  gear,gloves ,goggles that seal around the eyes,(try scuba shops )and  a respirator with an ammonia cartridge.

   I fummed a piece awhile ago, turned out really nice,just watch out for sap wood,(I assume your using white oak) turns it a cream color.Good luck..

   You don't need high strength ammonia. Household ammonia works very well and is less risky to work with. It may require longer exposure. I used an airtight container with a rack to hold the workpieces near, but not in, the ammonia. I never had to fume anything longer than 24 hours, and most pieces were only done overnight.

   Do it outdoors.  Lots of people have been killed by ammonia when it was a common refrigerant.

   I got some a while back at SSS which was Student Science Supply in Glendale or Burbank Calif. Chemically it's NH4OH. Just ask for "Concentrated Ammonium Hydroxide." Theirs is al lab grade (expensive). I don't know anyone who sells the industrial stuff in small quantities. Fisher Scientific in Chicago, if still in business, used to ship chemicals like this.

   Uncle Dunc is right, you don't need the industrial-strength stuff.  Ordinary household ammonia works fine and is safer.  Still dangerous, especially when you open up the tent - all that ammonia gas can really burn your eyes, nose, throat, lungs... but better than the 24% stuff.

   Look in your local Yellow Pages for a somebody who sells supplies to blueprint shops. That high-strength ammonia is used in blueprint machines.

   I used 12N ammonia in the past in chemistry lab. I will be carefull with it.

   I found a source. $30 a pint! I may try it despite the cost. I am turning some bowls out of red oak and want to see if I can gussy them up.

   Maybe I've missed something... Why would you pay $30 a pint for something when you can pay $3 a quart for the same thing?  As a couple of us have pointed out, ordinary household ammonia does the job quite well.

   I'll be interested in the results on red oak; I've only done it with white oak."Everything should be made as simple as possible, but no simpler."  A. Einstein

   Has anyone tried fuming mahogany?

   David Marks is said to fume both oak and mahogany with ammonia. I've tried oak (outdoors!), but not mahogany.

   Thanks,

   Whether you think you can, or you think you can't, you're right.

   Around my neck of the woods, ammonia other then household is red flagged due to methanphetamine.   You can buy it at fertilizer stores or ag centers but many times you have to sign your name etc due to scumbags making drugs with the stuff.

   It's anydrous (without water) ammonia that is used by farmers and used to cook meth. A totally different animal and you don't want to mess with this as it will pull your lungs out.

   I get a little nervous about being labled as a guy looking for NH3 because of the methamphetamine application. Also, I think it has an application in explosives.

   Kind of like looking for oak barrels durring prohibition.

   It sure does. If you dissolve Iodine crystals in conc. NH4OH, after a few hours NH3.NI3 (Ammonium tri-iodide) settles out. It's stable when wet, but a high brisance contact explosive when dry. Fun stuff, but I almost blew my hand off with it when a teenager.  Iodine crystals are used for treating thrush, a disease of horses' hooves. You can get it at the vet supply store, but they write your name down because druggies use it to cook meth.

   Rob,

   I think it is a lapse in judgement to discuss things like that.

   Couldn't you just collect all those left over samples in little specimen bottles from your patients.......:-)

   As for you becoming a wanted felon for mentioning backyard labs or dropping the "E" word over the web reminds me of the yarn about the old fella who wasn't able to turn his ground over anymore so he contacted his son who lived in the big city.

   Son wasn't able to help for a couple of weeks, by which time it would be too late to get his potatoes in, so he E-mailed Dad not to go digging up the back yard coz thats where the guns & ammo were buried. Within 24 hours the FBI had rolled up & dug up the whole yard, nothing there but Dad got his spuds in.

   I had a patient recently who ended up on a ventilator after using straight bleach to mop up a large amount of dog urine ( which contains ammonia). At least that is what i think she did that was so disastorous.

   Several people injure themselves every year, with some fatalities, by mixing household ammonia with household bleach.  The ensuing reaction liberates chlorine gas, which burns pretty much any tissue - eyes, nose, throat, and lungs. "Everything should be made as simple as possible, but no simpler."  A.
