Product Details

Copper sulfate is used for etching mild steel.  Sold in a 1-1/2 lb jar.


How to use Cooper Sulfate for etching mild steel.

Copper Sulfate is mixed in a 1 to 1 ratio with sodium chloride (NaCl - common table salt) to keep the copper sulfate from coating the steel with a deposit of copper that will stop the etching process and water. The blue solution gradually fades as the etching progresses and turns colorless when it's finished. Etching acids can be used more than once to etch steel plates. Each time the acid is used, it will take longer to etch a piece of steel to the same depth as before.

to make the Solution:

100 Grams Copper Sulfate

100 Grams (Cooking) Salt

1 Liter of (Warm) water
