Not easy to buy nitric acid anymore.Used to buy it at Kelly's drug store in San Andreas,Ca...The pharmacist would pour a half pint out of a big brown lab jug for me.They probably haven't stocked the acid in over twenty years.
In the 80s there were 2 in Reno and 1 in Moundhouse plus the late great Gold Divers there also. ALL GONE......sic sic sic sad state of affairs. Armadillo in Oregon used to stock many items new and used but a bunch of new owners over the years as sold/resold-I believe they still run ads.. John
Harrington and Baldwin Co. is a pretty new shop in grass valley. Went up in there once when they first opened. They are building their own high bankers now. Not sure if they have nitric.
I don't think I saw any nitric last time the hubs and I went down to Pioneer, and Frank is for sure still around and tinkering.
I am corrected and apologies to Frank for my misinformation. Must have been a different prospecting supply place a few years back. Or I confused retirement with, well....
