Question

What happens to the copper sulphate solution once a blade is immersed into it?

Answer 1

Explanation:

sulphuric/water bath. It appears that steel is taking the copper and lays up a nice layer of copper and it is a light color (not burned), however somewhere in the process this "foil" seems to slide off and floats to bottom of bath. I have even used a flashlight battery as I suspected the voltage was too high originally..but it slides off eventually too. whats the problem..too much acid.. not enough water. what concentrations to a gallon bath would be appropriate. Could the acid be burning up the bonding of copper to steel.

What would be an alternative to prevent rust from forming on say a steel knife. Looking for an easy simple solution.
