Christine here is a process report: Your backsplash is etched!
The drawing was made to size of fresh rolled out clay.
Below is a bag of Coarse Red Clay which I am cutting to place on the slab roller.
I used 60# of clay for all.
Above are the colors I selected thinking about your backsplash, from my shelves of commercial glazes.
Below are the tiny #0 and #1 brushes that I will glaze with. Three coats of each color.
Here is one of the three big tiles getting clay just rolled out through the slab roller.
Below the tiles are under drying boards and weight to keep them as flat as possible. They will be weighted for a week before glazing can start. Glazing is the longest part of the process, tedious, slow, applying glaze between the etch lines, it takes weeks.
Now everything is cleaned up and back under weight for at least a few days before I can proceed. Everything will shrink about ten percent as it dries. So far so good, things look great.
That is where we are in the process now. Hope these pictures give you an idea of how it is going.
I will post more photos in a week or so.
Working hard at glazing. This is as of yesterday but I worked today also.
Here is my kiln. I will not fire until 3 weeks after rolling out.
It has been ten days so far.
