21 Oct Copper Etching tests.
I decided to experiment with the etching plates and materials I use.
I have already tried and learned etching on aluminium plates, and dry needle technique. Now it was the time to try etching on copper.
After first tests, I can say the process is longer, but also it gives me more control on the depth and thickness of the lines I create, if I want a thicker line I cover the rest in the etching ground so it is not being exposed to the chemicals and etch only things I want.
I also like the “accidental” organic spots and skratches that were created because I added not enough of the etching ground.
2x45minutes + additional 45 minutes for few of the thicker lines.
