Handbuilt Tumbler Video

Last Friday, my video on making Handbuilt Tumblers/Vases was featured on Ceramic Arts Daily and it was great to get the responses from so many potters and artists. Looking at google analytics, I got hits from all around the world, majority from the United States. I had hits from every State except from North Dakota. Wonder if there are no potters there? And you can see the most are from California.

I enjoy sharing my techniques and it is always fun to see another artist's take on the same technique. If you try this technique or do handbuilding feel free to share pictures of your work in the comments section.

I got more confidence in handbuilding with slabs after taking a workshop from Ginger Steele, a potter from Oregon. I also saw a few videos on Yixing teapots from which I picked up other techniques.

Here are the steps for the process and the video

Cut template for your tumbler or cylinder from a thin slab (1/8 inch) of compressed clay. The clay needs to be a little stiffer than fresh out of the bag.
Roll the top rim with a brayer to round it making it comfortable for drinking. Roll the side of the slab to bevel it later for joining. The brayer can be purchased at a clay supply store.
Roll patterns or use stamps to decorate. This is where you can let your creativity show through. I make some stamps and some I purchase at thrift stores.
Apply slip to the sides and roll over a rolling pin to form your tumbler. To true up the roundness, use a round object like a Styrofoam ball which won’t stick to the clay.
Score and slip to add the bottom. The bottom is finished by running a profile tool (made from a popsicle stick) along the edge.
My tumblers are embellished with buttons to capture the look of embroidered fabric wrapped around and held together with buttons.
These tumblers are further decorated with slip to give more texture.

Final stages of decorating jars

A few weeks back I had blogged about the process of decorating my jars.

That was one of the earlier stages after which the pieces get bisqued. After getting bisque fired they look colorful.

But to have the colors pop out more, I go through the process of painting the groove lines that were carved with a contrasting color. It is a time consuming process but makes all the difference.These are then glazed over and fired again with the following results.

You can find these jars for purchase on my etsy shop.

Why do I need to learn Math?

Parents can admit that they have been questioned several times by their kids, “Why do I need to learn Math, Geometry, Algebra….?” And the list goes on.
I for one loved doing Math as a kid. For me it was a good pass time. Yes, you heard right, good pass time. When I was asked to study by my parents and I used to always pick Math. My parents had to push me to study other things. As I grew Math and Physics became my favorite subjects.
Of course this did help me in acquiring my current job as a software engineer. So you are wondering why I am even mentioning this in my art related blog.
The fact is that I see myself applying my knowledge of Math in my art work very often. A good example are these big jars I made recently. Of course, one option was to throw them on the wheel, but I wanted to make them big and much lighter and consistent in size. So I decided to make them from slabs of clay, a technique I got more confidence after seeing the work of Ginger Steele.
For the walls, I could make straight cylindrical in shape, which would involve cutting a rectangle and joining the ends. But what if you want it slightly tapered? I would have to have a curved slab, but how big? What curve? What radius? What angle? That is when geometry and Math help. I spent several hours designing the shape that I wanted and then trying to figure out the template for the slab I would need to achieve the shape I wanted. Here is a small snippet of my scratch pad. Oh yes.. it sure has some Math there.
Once I figured out the size of my template, it was a lot easier to construct these jars. Once I knew I had the template right, I didn’t have to struggle with the shape that I wanted. The top lid seats and lids have been thrown on the wheel. I still need to go through the process of decorating them, but at this stage I am happy with the way they turned out. I will post more pictures when I am done with these.
So tell your kids to stick to Math, even if they don’t know where they will need it. It will surely benefit them in some way or the other.
