You could buy it at a Farmers CoOp in 50#bags for about $15.00 before the Oklahoma City Federal Building bombing. I bought a bag about 20 yr. ago.
Sodium Nitrate is also one of the components of Alkaline Hot Bluing which I have a formula for.
If anyone is interested I can dig it out but I must caution that it is a molten salt bath very Hot.
