I’ve had a productive week. Sixteen mugs, three small bowls, and a vase thrown on the wheel. I ran the risk of not getting handles attached to five of the white mugs and getting their bottoms trimmed up; I had left them to stiffen a day too long on the shelf, so it was a scramble in getting them trimmed, pulling handles and getting them on. As I was working I knew there would be cracks at the joins, and I really thought I’d missed the window, but with a good roughing and lots of slip I hoped for the best. Then I went on to work with red clay.
Sure enough the next day when I checked the white mugs they had indeed formed cracks where the handles joined the mug. I set to work with a paint brush, vinegar and a flat, wood tool and mended the fissures. I had to do this every day until all the pieces were completely dry. Why Vinegar? It moistens the semi dry clay without adding extra water to the clay because it quickly evaporates. So it gives me enough time to manipulate the softened clay to make minor mends.
Luckily I managed to save all the white mugs. The red clay pieces were carefully monitored as they set up. Then I spent a day trimming the bottoms and pulling handles and attaching them. But checking them the next day I spotted a few of them had small cracks, so out with the brush and vinegar.
I have been making a lot of mugs, trying to get them right. When I first started making them they came out of the kiln so small, not taking into account how much shrinkage happens. Then, when I think I have a good size mug and glaze them, I’m unhappy with the end product after the final firing. In the last firing for example the clear glaze applied over top of the underglaze, was too thick and caused some lumpy and cloudy areas in the final fire. So, trial and error, and practice, practice, practice.
I think I’m getting closer to the size I’ve been after, and the thinness. Tomorrow I’ll be under glazing. I’ve stumbled upon some designs I was quite happy with on my last batch and I’m excited to get to work. Fingers crossed this batch is the charm!
Then I made a mini-Apple Pie and Orange-Fennel Ice Cream, because- balance.
