Etching Steel

First - thank you Leslie Kail Villarreal for her inspiring video on how to etch  steel

I did use 3" x 6"  (.125) Hot rolled steel - you just have to clean the scale off with some elbow grease and  steel wool (although I could have used muriatic acid to clean it as well )  - I cut a pattern with my scan n cut machine using 651 oracle vinyl (going to try pnp another time )  and used both the negative and positive image and used both sides just to see how it etches.


I bought the glass vase at the dollar store  and used a metal cake pan for underneath.  I had an aquarium pump from my pysanky eggs and just cut a piece of the tubing to use to bubble and clipped it to the edge with a plastic clip - from the dollar store .  I also got a plastic pitcher to mix the water, copper sulfate and salt  then put my piece in  and poured the mixture in - 2L is enough to fill this vase to the top.  2L is  1 cup of copper sulphate   and 1 cup of salt (I used the pickling salt - no additives ) and then filled the container up to top (2l mark) mixed and mixed till disolved.


So it was soooo green and bubbling - after 1/2 hour took out and used a soft toothbrush to brush off some of the copper build up then put back in.

once finished just brush more and clean off - the hardest was puling off the vinyl with tweezers


cant wait to try it out in my rolling mill 
My notes : 

Next phase is to test out using my PNP blue which is easier to use - and can do more details as well - and I want to go revisit my steel washers  for pendants if you remember 
I used pnp blue for the pattern but the etch was really for copper and not strong enough - this formula gives a really good etch  so will try it this weekend - go here to find washers
