I started them last week, just before my basement flooded and my studio became unusable. (It was a sad day, and I've been in a funk ever since.)
So I moved the small kiln up to the dining room to finish them up.
To make these, I put a thin layer of grey frit on top of the green coasters for the initial firing. Then I sandblasted away the non-fish part.
Before refiring, I had to add some additional frit to make the fish stand out a little more.
