This week I will be showing you a very old technique known as etching. I absolutely love the results that can be achieved on metal this way but I will say working with Etchant, the chemical you need to make the process work may not be your cup of tea.
Etchant is sold at places like Radio Shack. It is mainly purchased by computer repair people who need to remove copper from computer parts. I work very carefully around this chemical. I wear gloves and I dispose of the left over etchant at my local Recycling Depot. I also only work in the garage.
The only other product you need is baking soda which stops Etchant from continuing to etch.
You need to decide what you want want to etch. I like to use rubber stamps for the imagery. Others like to draw their own images on metal.
You need to draw with a permanent black ink. You can use a solvent based black ink pad or a black sharpie market. All you need to remember is that whatever is black….will not be etched.
I am using copper blanks from the Metal Complex line. You need to clean your metal thoroughly and then I use a little steel wool to do a final clean.
I stamped this famous face on several copper square blanks.
Now we wait a few hours. In one hour, the metal will be etched. For a deeper etching, you need to leave the metal hanging longer. Some people agitate the bowl every 15 minutes to move the etchant a little.
Tomorrow, I will start to show you results!
