Last week I happened upon videos about kitchen lithography. It got me very excited! I couldn’t wait to try the process out for myself. But, what occurred to me was that it was the acidic properties of cola that was responsible for the etch. This led me to believe that white vinegar might be a more practical alternative to etch with. Practical in the sense that it’s just as acidic as cola, can be re-used many times, thereby becoming more cost effective. As you can see by the results on the video, the process works equally as well using white vinegar as the etch instead of cola. Here is a list of the materials you’ll need to do the process yourself:
1. Heavy Duty aluminum foil (Use dull side to work on)
2. Gloves
3. Litho crayon
4. Piece of plexi-glass
5. Vegetable oil
6. Paper towels
7. Plastic tub
8. White vinegar
9. Water
10. Etching or relief ink
11. Brayer
12. Sponges
13. Trays for water
14. Paper
15. Spoon or etching press
I plan to try more experiments using white vinegar in the future. Will post more results for you to see.
P.S. I had two semesters of lithography at community college so I know what I’m talking about. 
(ha ha!)
