work you got the steel hot and plunged it into oil, but cant remember
how hot, red,yellow?
>I have used a recipe for hot bluing salts with excelent results....
Standard salts need Amonia Nitrate, Lye, and Watter... When the amonia
nitrate hits the Lye and watter mix, HUGE ammounts of amonia gas are
released, making it verry bad for anything alive.... You can replace
the Amonia nitrate with nitrate of soda(avalible at any nursery)...
Since all you need is the nitrate.... It is hard to find pure lye now
since Red Devil stopped making it, so you need to go to either a soap
making store, or someplace that makes bio-disel, since they both
require pure lye... Here is where I got the recipe.... If you do the
math, you can figure out how to make a verry small batch just large
enough for your part...
