Aging pots

Lately I’ve been experimenting with ways to age pots more quickly, making the crackle stand out. This time I tried an old woodworking trick, and it seems to work nicely.

I soaked the pots in a strong tea bath then dried completely.  After that, I applied iron acetate with a brush and let them sit a couple of days. The iron acetate reacts with tannins and turns a dark color within about 3 days. I made the iron acetate by soaking steel wool in vinegar. I may change to a weak sulfuric acid solution, since the smell of the vinegar is proving difficult to get out of the pots!

At long last…

… some pictures of new fired/finished work. Finally got my brightness and white balance issues resolved and took a few pictures to share with everyone.

I hope you enjoy them…

Plates for February

Here are some of the things that will go into the Feb. firing. Small plates that will be about 12cm fired, and some larger plates about 24cm fired.  Clay body is Karatsu white from Hara san and Kishidake clay 50/50, with pulverized sandstone and weathered Shirakawa porcelain stone wedged in.

Shirakawa Porcelain Mine

Took a hike up the mountain today to the now closed Shirakawa Toseki (porcelain stone) mine. This was the base ingredient for Arita’s glazes for hundreds of years. The mine is extensive, but I stayed near the entrance as old mines are not among the safest places on this earth. The passages from the main entrance radiated out in several directions and where light still filtered in, you could see that some of them extended several hundred meters. And that is just what you could see from the light filtering in. Who knows how much farther they go?

In the entrance area, pillars of rock were left to hold up the roof, but there were boulders in several places on the floor, from what looked like recent rock falls. The roof of the cave is probably about 20 feet tall. The expanse of white rock is really stunning to see.

glaze crawling a bit

There was a bit of an issue with crawling over one of my clay bodies, when raw glazed. The guinomi toward the front of the kiln had this problem, but melted enough to look interesting. These bowls at the back just look dangerous. I left them after the last firing, but finally got them out yesterday and had a nice cathartic smash fest.

Karatsu Show

This last weekend we had the show in Karatsu.  It was a 3 day weekend, so we did Sat, Sun, Mon. Well, if you are thinking about having a show on a 3 day weekend, let me give you a little advice: don’t. Everyone goes somewhere else. The first two days were absolutely empty, and it was only the during the last day that I was able to make some good sales. Thanks to guests from Osaka, Kyoto, and Chiba. I guess they were using the 3 day weekend to get out of their respective areas as well.

Well, lesson learned. Overall, it was still a very enjoyable experience, with lots of time to sit and chat with friends over tea. The highlight of the show was without a doubt, the shiboridashi teapot with the river crab knob. It is a pure silver crab holding a ruby in his right claw.
