Such is the case with my cupcake plates.
I designed a really cute pattern of sprinkles and candies for the top of three cupcake plates. One was vanilla with a blue wrapper; one was strawberry with a green wrapper; one was chocolate with a yellow wrapper.
The deal with ceramic glaze is that you just don't know what it's going to look like until it fires. The color out of the bottle is rarely ever the color it fires to in the kiln. Shoot, I have to paint my pieces solid blue or solid green to get a gloss finish on them. So designing plates with this much color is problematic at best. Even if you've used the glaze before, it's unpredictable.
The vanilla cupcake turned out better than I expected. It's shiny, it's evenly colored, and it looks delicious.
But then I saw the Strawberry plate. It's...bizarre. It bubbled, it got rough, it under-fired in the center of the plate (normally happens on the edges if it happens at all), and shot off a few spots completely in the back.
Am I mad? A little bit. These were a pain to put together. I'm too embarrassed to show the chocolate plate that came out a mix of purple, under-fired, and delicious dark chocolate. I soldier on. I'll be able to fix the other two plates. It's just a minor setback I figured I could have avoided. No such luck.
