Today I tried etching! I have been thinking about it, reading about it, and wanting to try it for at least 3 years (yes, I must be patient, everything in its own time).
So today, my son and I took a trip across town to the electrical store and I purchased Ferric Chloride, the etching solution. It is a salt based product and not an acid...better. A quick stop at the store on the way home to get a basin to contain the solution and I was in business.
I really didn't have a specific design in mind, so I drew something...anything to see how this works...finally...
I forgot to mention that I also purchased a resist pen. Although I understand that a permanent red marker works, along with nail polish, etc. It just seems strange to me that the stuff eats up copper...but won't eat through a marker? Yes, I understand the chemistry of it...but it still seems wierd!
I stuck a piece of packing tape (yea, won't eat that either)to the bottom and suspended the plate of copper with my drawing in the solution. I checked it about an hour later. It is suposed to take from 1 to 4 hours, or so.
Life continued and I had to babysit my granddaughter, Chloe. A "couple" of hours later I was able to check my now "perfectly etched piece"...
The etching solution worked, I am not sure at what point of time my piece was etched to perfection...all I know is ...it was way past that point of retrieval...the tape remained in tact... but only hints of thin copper and faded resist existed now...I HAD SACRIFICED MY PIECE...I HAD FED THE COPPER GODS...
