Yes, I am using the Beutel formula on page 88, and it has 1.2 grams of copper sulfate and 3.0 grams of ferrous sulfate.
Damascus, I greatly appreciate your suggestion, but Im a measure twice, mix once kind of guy. Im certain I made the solution correctly.
I applied it when the surface is warm, which is my practice so it drys quickly.
If this is because of the copper sulfate, why is it so frequently used in bluing solutions? What does the copper sulfate do?
No, my tanks are not brazed, it is stainless.
