No More Pure Ammonia In Canada

[VinceInMT]

I don't know what I am talking about except that back in the day when I worked as a drafter I ran lots of blueprints through our machine and the "developer" came from bubbling air through a bottle of an ammonia solution. I remember that the contents of the bottle were quite a bit more concentrated than the household type. A quick look online showed that one can still purchase it (in the states anyway) and it's listed as 29.4%.

Anything outside of Canada is no good to me. It'll get stopped at customs.

I hear you. You might inquire at some older engineering/architectural offices and see if they have some old bottles laying around. Most have switched to plotter drawing but there might be an old blueline machine and developer stashed in a back room.

Great idea, thanks!
