I had some plates at home to start with and used them as practice. The first three are these:
I then went to Dick Blick online and searched for pens that would work on glass or ceramic- anything shiny and hard basically. And to my surprise, it showed me a pic of pens that I had already purchased for their color. I had gone to Michaels craft store and bought a couple sets for coloring as it looked like fun to add to the classic black and white zentangle. So many of my fellow tanglers are great at using color to make beautiful art. I wanted in!!!
Here is what happens if you put even these tough inks into the dishwasher !!! It completely removed the sharpie ink and as you can see it faded out this 'waterproof' ink. It did say waterproof--it didn't say dishwasher soap proof!!! Apparently that stuff is powerful!!!
Now we get to the work of putting a design onto a plate. Because they are a circle generally, a mandala is a perfect start for a round plate. The tracing below was used on the red plate. To get the shape on to the plate you can see below that I used blue chalk, and then added pencil. On some plates the blue chalk was fine, but on others the mat surface took the pencil better.
This part of the job is definitely the trickiest part. You center the design as best you can on the plate without getting your fingers on the paper over much. It will leave smudges of pencil where you are trying to get lines to show. I trace the design with a pencil and then remove the paper. I immediately put my ink onto those tracings, and use the pattern as a guide for any questionable lines. If you don't do the ink quickly you will take a chance of messing up the lines, and I find my muscle memory is better for doing it a second time right away. The lines are faint, but you just drew them, so you can do them again!!
This one has drawn in shading...
This one has brown color added to the black..
