Frit Cast Experiment

During the year, there are times when you have more time to experiment on new work. For me, this typically happens at the beginning and end of the year when there are no shows. You may recall my post at the beginning of this year about making frit.

Well, one of the projects that I hoped to make was frit cast bowl. I had taken a class and made a 4.5" frit cast tile using only two colors of glass.

So, I hoped to use the technique to make a 12" bowl. I weighed the frit and fired the kiln. Unfortunately, this did not turn out as expected. This is because I measured the frit based on having 2 layers of glass, whereas my tile was based on a more than 2 layers. The technique was based on mounding the frit and having it spread out. Thus, I didn't have enough frit to nicely melt to the edges and the glass was at least 1" shorter than the intended 12" circle and of course, not uniform in thickness (thinner at the edges, thicker in the middle).

But not to waste anything, I've cut up the glass and incorporated it into the center of a plate.
I like the detail that you get from from the frit and could see doing more of these but adding more colors and making the frit more random (e.g. think of various colors of frit shaken up).

And, I'll still try to make that frit cast bowl. But, next time, I'll be more intentional at laying out the frit so it completely covers the base rather than mounding it and adding more frit overall. Once I get that done, I'll post it but most likely not until the end of this year or beginning of next, when I'm back to experimenting :)
