Ceramics and Glazing

I signed up for advanced ceramics this semester, having taken my first ceramics class well over a decade ago. I realized, very quickly into my class, that my previous class meant that we had been mostly just baby-sat by someone who knew how to work the kiln. When it came to glazes, we had "The Wall of Mystery". Meaning there were a -whole-lot- of commercial glazes... and not a one of them labeled-- no idea what color they were going to be; no idea what temperature they were meant to be glazed at.

So I'm learning an infinitely larger amount about ceramics than I ever have before. To include mixing our own glazes!

Our first assignment was to create 6 bowls, of which half would be donated to "Empty Bowls"

Event raises funds for food bank

Empty Bowls can feed the hungry.

That’s an odd thing.

But that’s exactly how the Empty Bowls project works.

Kim May, director of the Pike County Salvation Army, said the purchase of an “Empty Bowl” will help feed the hungry in the Pike County area. Then, that bowl may be filled with a choice of several soups to be enjoyed in the fellowship of friends and neighbors.

The Empty Bowls luncheon will be from 11 a.m. until 1 p.m. Friday at the Colley Senior Complex annex on Elm Street. Tickets are $20 and include a handmade ceramic bowl of one’s choice and the soup lunch with beverage and dessert.

“This is the second year for the Empty Bowls luncheon and we expect it to be as successful as last year’s event,” May said. “All of the bowls are handmade and are worth more than $20 apiece. The bowls were crafted by artists who have participated in the Alabama Clay Conference, by Larry Percy and several of his pottery students at Troy University and by the pottery classes at the Colley Senior Complex.”

There will also be bowls handcrafted by local celebrities and those bowls will be offered as silent auction items.

“We have several celebrity bowls that have been completed and expect several more by Friday,” May said. “Celebrity bowls have been made and donated by Jerrel Jernigan, former record breaking wide receiver for the Troy University Trojans, Troy Mayor Jimmy Lunsford, popular radio personality Ralph Black and Bear Woods of the Atlanta Falcons. Troy University Chancellor and Mrs. Jack Hawkins, Jr. designed a special bowl for the event and it will also be a silent auction item.

May said the funds raised by the Empty Bowl luncheon will be used to stock the Pike County Salvation Army food bank.

“All of the money that is raised will stay here in Pike County to help feed those in need,” she said. “So, we invite everyone to join us Friday for the Empty Bowl luncheon. Come, pick out a handmade pottery bowl to take home and enjoy lunch with us. The weather should be nice so we plan to have tables set up outside for those who would like to enjoy the sunshine, as well as tables inside.”

The “fillings” for the Empty Bowls will include camp stew, chili, chicken vegetable soup, beef stew, potato soup and professional chef Ron Case’s tortellini soup.

May said there will be about 100 Empty Bowls to fill and the belief is that this year’s effort to feed the hungry will reflect the generosity that has long been a trademark of Pike County.


The event happened today-- and we were pulling the bowls out of the kiln up to 10 minutes before. We were going to pull them on Thursday, but they hadn't fired completely and we wanted to be absolutely certain that they were going to be food safe. So we immediately fired them again, and it was a success! I decorated 4 of my own bowls, and 2 from previous students that had donated their bowls for the event, and all 6 of the bowls fired properly and got to go to the fund raiser!

That said, the reason this blog is called "Ceramics and Glazing" and not "Empty Bowls" is because I want to share the process from making the bowls through glazing them. Because if you're like me, you never would have known that the colors applied to the bowl don't often look -anything- like the finished colors-- and that because glazes are glass, the high temperatures make them flow like a liquid-- so no matter what you -think- you're going to get, you don't really know until after the pieces come out of the fire.

...which is why I'm semi-obsessive about taking process photos (lol).

Bowl #1

This, right here, is the first bowl I've every successfully thrown on the wheel (: When I took ceramics the first time, the baby sitter tried to teach me to throw with my fingers-- and I couldn't do it because I was triple jointed. This semester, I've been learning to throw with my palms-- and boy does THAT make a world of difference!

These are the images of the glazes I put on it. I have to admit, I absolutely LOVED the way it looked copper on top of blue grey before I fired them.

And if you want a very dramatic example of what I mean when I say you don't know what's going to happen until the firing is all done, then look at the next images....

See the mottled brown and yellow bowl in the center? That's it after the first firing.

And this is what the bowl looked like after the final firing. My time consuming, lovely design simply flowed away and vanished.

Bowl #2

We were also required to make a thown bowl with straight sides and a handle. I made this one (:

Then I decided I wanted to glaze it in burgundy (which is the green below) with a black spiral (which is the brown) and make it a pinker burgundy (called 'Raspberry') on the outside.

I was quite pleased with the way it turned out after I painted it. But then we fired it...

and I learned that even though it looks like you might have covered all the surfaces when you painted the glaze on-- that's not necessarily true-- and if the ceramic body is exposed, then the bowl is NOT food safe. So instead of trying to repaint the burgundy, I covered the entire bowl in a clear glaze.

This is what the finished piece looked like. Yes, the colored glazes are not as thick on the piece as I would have liked, but the clear glaze over it assured that it is completely food safe.

Bowl #3

I decided to get more creative with the glaze on this one (:

Have to admit, I LOVE the designs! The colors are supposed to be white and black after firing.

and they are (: But after the first firing, it was still chalky, so it wouldn't have been guaranteed to be food safe.

This is what the piece looks like after the final firing. And it was also ready to go to the fund raiser (:

Bowl #4

Admittedly, this one is -almost- like a plate. I didn't get a chance to take a picture of the painted/not fired glaze but what I did was a yellow butterscotch spiral from the center, then dipped the entire bowl in a green color called celadon that is -supposed- to be translucent...

...Yeah....I don't see any yellow or butterscotch either (;

And below are the donated bowls of other people, that I glazed.

This is actually the first bowl that I glazed. My husband loves the thumb hold that was put in this bowl, so I'll probably throw a bowl and try to reproduce this one. I swirled 3 different shades of blue from the center and painted the outsides a different shade of blue from any of them.

I -really- liked the way it looked at the first firing, but it hadn't flowed and wasn't food safe, so like all the other bowls, I glazed it in clear and hoped for the best.

The finish piece is smooth, shiny, and the swirl is -much- more subtle.

Working in black and white again (:

After the first firing, but with some of the clay body exposed, so I clear glazed it.

And the finished bowl was much, much more subtle, but still very pretty. And I learned that the black shows up on the white much better than the white shows up on the black.

That last sentence is actually pretty important, because the entire process was a learning experience-- I still have 6 bowls of my own left to glaze and decorate. But now, I'm not going in completely blind to that process and have a better idea of what works and what doesn't.

After I get those taken care of, there'll be another post just for them, and we'll see how well I payed attention to this week's lessons (;
