Surface Decoration Techniques, Part II

Image
I continued working on surface decorating at last night's class. Over the weekend I had finished the sgraffito piece, so I just had to set it out to dry: I call this one "Apatosaurus Under the Rising Sun". Or something. Anyway I quite like how it came out, though it was a little difficult keeping the edges of the carving smooth. I also made a third plate with the scraps from the last 2 plates (which was a weird pain; the scraps didn't seem that dry but were very hard, so it took a ton of wedging): It's not very exciting yet, because I want to do slip trailing on this one. That means using a squirt bottle type thing with a very thin nozzle to draw a design on the clay using an underglaze. Unfortunately the underglazes have to be prepped for that. They have to be pretty runny and there needs to not be any clumps, so they actually get forced through a sieve. Our teacher will work on that before the next class, so I'll be able to finish this on Saturday. ...

Adventures in Surface Decoration

Saturday was the second class. I just continued work on the things I started in the first session, primarily making small plates of cone 5 b-mix to experiment with different surface decoration techniques. I finished this plate using the mishima technique: That means I carved the design into the leather hard clay, then painted it with colored underglaze. After that dried I wiped away the excess with a damp sponge, leaving only the lines colored. Unfortunately I think I had my sponge a little too damp, so in some places too much of the underglaze was washed off. I'm hoping I can touch this up after it's bisqued, if necessary. I call this one "T-Rex Under the Moon". Next, I made a second small plate: This guy was painted with underglaze when it was leather hard, and then at home I carved a design into it, per the sgraffito technique. So it's basically the opposite of the other plate. I'll post pics for that later. It turned out mostly ok, though the lines...

Glaze Day

Saturday, August 3, was Glaze Day. As it happened, I only had a single thing to glaze: my teapot. My spoon rests were still being bisqued, and everything else was fired using an alternative firing method (my flower was still in the process of being soda fired, in fact), so the teapot was it. This turned out to be a very good thing, as it took an inordinate amount of time to finish the teapot. I painted it with underglazes, so it was a very meticulous and time-consuming affair, as I had to make sure all the nooks and crannies were colored, that there was even coverage and no splotches, etc. I was at it for at least 2 hours, I think. I painted the eyes blue, with black pupils and lighter blue lines in the irises, so they aren't so monochromatic. I painted the hair and eyebrows black, then added small lines of brown, to try and give them some depth. Finally I painted the body and trunk light grey; I tried to thin out the glaze a fair amount as I was a little worried it might come out ...
