So I tried this new copper etching technique that I found posted online and I thought it worked amazingly. The best part about it…. NO MORE HAZARDOUS CHEMICALS!!!!
supplies:
plastic container
copper wire
alligator clips
rectifier or battery charger
water and salt
copper blank
patterned piece
Take a plastic container and fill ~1/4 of it with salt
Fill the container with water
I have a rectifier that applies a voltage to my alligator clips…a rectifier is also used for electroforming….but I have seen videos where people have used battery chargers. (you basically need a positive end and a negative end to attach alligator clips)
You will need an anode and a cathode
* anode is the piece you will be etching
* cathode is the piece you will hang in the water to collect all the copper ions
Hang your piece to be etched and your blank piece of copper from the side of the plastic container using copper wire.
Attach the red alligator clip to the copper wire that is hanging the anode (*piece you want the etched pattern on)
Attach the black alligator clip to the copper wire that is hanging the cathode (*piece to collect the copper ions)
plug in your clips to the rectifier and turn the voltage to 5-6 voltages.
Etching copper at this voltage takes about 1-1 1/2 hours and makes a nice clean deep etch!!! No Chemicals No Mess….and you can reuse the etch over and over!!!!
