Oh Yeah!

So this is pretty much what the etching process looks like..You draw the design in mind directly to the metal using your oil based art pen..Pour a etching mordant/acid into a glass bowl or plastic polyurethane bowl..Add your pieces..I forgot to buy tape but its much easier if you add a strip of tape to the back of your pieces and tape it to the edges of  the bowl so that only the surface of the metal dips into the acid..Leave it in for atleast 20-30 minutes the deeper you desire the etch the longer the time you leave the pieces in.Remove with tongs and clean peaces off using steel wool.
