What can you etch copper with?
Ferric chloride works on copper, brass and nickel silver. It will not work on actual silver (fine or sterling). Do NOT use ferric chloride on aluminum. Metal as thin as 24-gauge can be etched – just leave it in for less time than you would for thicker metal.
How do you engrave copper?
How To Etch Copper In 8 Simple Steps
- You’ll need: Acid etching solution (ferric chloride)
- Safety first…
- Prepare your copper sheet.
- Choose your design for etching.
- Add resist to your blank.
- Carefully prep your copper with tape.
- Leave your copper blank in the etching solution.
- Neutralise the acidic solution.
Is copper easy to carve?
Copper is sharp and it’s easy to get cuts on your fingers.
Can you etch metal with vinegar?
Boiling down the vinegar to 20% will work better. Boil down 4 gal to one to get 20%. The amount of time left in depends on how long it takes to give you the desired etch. You have to use some steel wool every couple hours to clean off the oxides.
