Glazing idea

p1050548

April is around the corner.  It was snowing outside.  We always have the tug of war between the winter and the spring.

Kiln is loaded, and ready to go tomorrow. No wind in forecast.

Sometime glazing idea comes from the imperfect firing result.  Here is one.  This bowl is supposed to be look like on the left, but the glaze just dropped during the firing (photo on right).  I liked it, and tried the duplicate design, purposely, by brushing the glaze.

Glaze test

Last two firing, I put a couple of test glaze. I was aiming the chun blue, and got this amber color. I like it actually.

I was glazing today, and noticed this cup on the glazing table. It looks like the chun glaze.  Bottom of the cup shows  2000 by me. I totally forget about I had this glaze. This will be great with my tenmoku glaze. I found the recipe in the hyperglaze program, and will mix it tomorrow for the next firing, which is on Tuesday.

Old Albums

The other day, I was looking for a Japanese pension card, and digging through boxes of albums. My daughter wanted to see the albums, so we browsed through them. We were looking at a picture of Varanasi , India, and she said this is 30 years ago today. After traveling around the US in Greyhound buses, I took my father to Nepal and India for a month for his sketching trip. We did not make any reservation in advance, and went where we wished. I hated it when I got home, but strangely I wanted to go back very strongly, six months later or so. I have never gone back though. People were very pure and seemed happy, except ones exposed to foreigners. Toward the end of the trip, I was negotiating for a long time over 1 cent. I thought that was a very important thing to do. The value of the money was different, I heard they earned $30 a month, and if you give a dollar for tip, they just became beggars.



Went Kathmandu, Pokara in Nepal, Varanasi , Taj Mahal (Agra), Jaipur in India. They had gorgeous and beautiful landmarks, but the market (Bazaar) and people fascinated me the most.

At the Varanasi , we went to see the River Ganges early in the morning. Probably we shouldn't have, due to the Sacredness of it. Anyway, by looking at the people's activities, bathing, cooking, praying, playing and cremating within a stone throwing distance. Life was just concentrated in one spot. The cremation, I still vividly remember today, how people looked happy around there. I thought that 's the way to go. I probably did not see sad part of ceremony.



In Nepal and India, literally mountains of bisques potteries were displayed on the street. We went to a pottery town, they were using a truck tire as a pottery wheel for making cups. They were serving the chai with these cups at the market, or even in the train, and they just smashed it once they finished drinking. No plastic or paper cups. Anyway, I saw a potter making large water storage jars, by coil building. He was making them very quickly and preciously. He was an unknown crafts person. He started to build a top rim of the jar, and built up a cylinder. He widened and rounded the shape by using a wood block. Once dried enough, it was flipped over to the bowl shape mold with sand and a slab of clay, and joined together.

Kiln Unloaded

p1050525


After two and a half years of trial and error, I finally got a whole kiln reduced at my studio location. It was very calm day on Friday, and might be the reason why. I hope not. I changed the two things, at up to and during body reduction period, and the soaking period. I tried to fire the bricks first, not pottery, as I read one of Japanese pottery book long time ago. I candled the kiln longer, and used the blower at the stronger setting while closing the flap than usual to push the heat until the end of the body reduction with lower gas setting. Second, I put the kiln back into the heavier reduction on the soaking period for 30 minutes. This is not usual way. The way fired pieces look, the turquoise glaze shows the sign of the oxidation, but reduced on the glaze used for decoration, such as red/pink in reduction and pale in oxidation. It seems that the oxidized part of the glaze was reduced by this process. I fired once with the heavier reduction (less air from blower) all way through, which was very bad firing, lots of crawling if I remember correctly. I wish I've taken the detailed note on each attempt.


I do not know either or both processes helped this firing. I am pleased with what I got. If the next firing goes well, I will be out of the woods, for now.

Lose some and gain some...

Trimming and attaching handles to pitchers. As I trimmed while water spray on my hand, I could see the ware getting drying in front of me. I had bisque firing yesterday, and the studio is very warm just from spring-like sun. It was very dry... I brushed the wax around the handle to slow  drying and covered them with plastic before I left.

Good news is the berry bowl I trimmed the day before looks ready for the bisque.

Satisfactory kiln opening

p1050503p1050509

Opened the kiln today. Still having the oxidation on the bottom shelves, but the rests of kiln are good.

The reduction agent reduced the rutile blue glaze, but pitted very badly. I may apply too much. Need further testing.

p1050506

I am starting to catch the glaze bug. There was a test pieces for the celadon blue glaze, which does not craze, but got yellow-ish color. I sorta like the result, though. I used 1% of black iron oxide. I will try with 1% red iron oxide next time, and apply more thickly.

Night after

p10504911p1050493

Last night, we had great turnout, and people enjoyed our building to offer. It was pleasant surprise to me. Last time I opened the studio, I, being in 4th floor, had 2 people while people downstairs got close to 50 people. This time, Crocus Clay Works organized the great event, and there were flow of people moving the floor to floor. Thank you very much for coming, and hope to hold the same event in the future.

Today, I waxed the bottom of pottery for glazing. If you do not wax or wipe off the glaze from the bottom of the pottery, it will melt and stuck to the kiln shelf during the firing. I use the sponge brush for this. I buy a large volume when they come on the sale, like 10 cents each. With this, my hand is pretty much wax free during the process. Wax, of course, repels the glaze on the area covered with, unwanted glaze is easily wiped off with wet sponge.

I am experimenting a silicon carbide in this kiln. I have one area of kiln got oxidation. I read somewhere that the silicon carbide is the reduction agent, and helps the reduction. I mixed the silicon carbide with slip of clay, and

brushed on the side and interior of the bowl. I will glaze this bowl normally, and place it the area of oxidation.

p1050496

I will glaze next two days.

Hidden Hungerford, Tomorrow 3/6 5-9PM

p1050487


We had the walk-through of participating studios yesterday. It was fun, and I did not know so many great studios in the same building, from paintings, photography, quilt, to stained glass. It was like walking the galleries in SOHO.


My studio was messiest of all, so I decided to clean up a bit today, and placed some shelves on my drying racks.


If you are in Rochester area, please stop by. It is worth the trip!

TV watching in studio

p1050473

The studio is almost full of bisque and ready-to bisque wares. I hope to do at couple firings next two weeks. Outside is 17F degrees today, but the sun was getting quite strong. I enjoyed the sun! During the winter in Rochester, NY, it tends to be gloomy, and the sun is rare commodity.

I have been watching TV show, Lidia’s Italy. It opened my eyes on the Italian cooking, very simple but complicated taste and textures. I never thought the shape of pasta for the texture. She cooks up the spaghetti sauce while cooking pasta! This is tonight spaghetti, pancetta (Italian bacon) with tomato sauce. Took me less than 20 minutes and was very good. The other day, I tried the cauliflower and squash in tomato sauce. That was super good.

We use this pasta bowl a lot at home, from pasta to curry.
