A lot of the Nitric acids I have seen for sale on eBay, tout them as chemically pure, lab grade, or some other description as a super duper, the bomb stuff. With it comes a very high price. Most of this is not what it is represented as. The labs that need the certain grade of Nitric they require, do not purchase it from eBay. They have their sources that they have used, tried and true.
Last time I inquired about Nitric at several large chemical supply houses, they did not want to bother with even a 5 gallon purchase. 55 gallon drums minimum, was what the majority of them had readily available. $1,500 US was the approximate cost for 55%, High density Poly Ethylene drums, $100 deposit for drum.
I have a boat load of pure Tin, and about 20 pounds of 90% tin, 10 % bronze. I was thinking at one time of making prills, and selling them here. The cost of Tin these days is around the $9.00/lb. mark. If I sold 2 ounces of prills, ( which would last most on here about 10 years) plus the $7.50 cheap shipping rate, that would equate to around $9.00 for a 2 ounce purchase from me. This does not include any money added for my expenses of the prilling and packaging, and taking time to drop at the post office. UPS would be even more expensive. That is why I never followed through on the Tin project, posted under some other thread on pure Tin acquisition, many months ago. Tin alloy solder will work, and you get more from the chain store, then you would from me. So divvying lots of Nitric would be a major PITA. That is the reason it is hard to find in small lots. Go big, or go home. Unless I had absolutely nothing to do, I would consider doing this. Unfortunately, I am super busy. Patronize our sponsors, it is not a crime to make a dollar. If you want to make a buck the hard way, try dispensing small lots of Nitric.
