To wedge the clay, you use the palm of your hand to knead (repeatedly pressing) the clay. You keep kneading the clay until there is no longer any air pockets left. Cut the clay in half to reassure that there are no air pockets. If there are any left in the clay, there is a high possibility that the pockets could blow up in the kiln. This event could harm your projects as well as others.

To roll the clay, you have to make sure your clay is wedged with no air bubbles. Then, you take the desired thickness of the wooden sticks and place them on each side of your clay. While rolling the clay with a rolling pin, make sure your clay is spread out far enough to fit your required base size.

After you roll your slab, you will have to cut out a circular base using the knife tool. Also you would have to use a measuring stick to make sure your base is the right size for your coil pot. 

The next step is to roll a long cylindrical coil to make the height of your project. While rolling your coil, use your hands and roll the clay into a long cylindrical coil. After finishing rolling your coil, place around the base of the clay and cut the coil to the right size. You want to make sure that you have the coil going all the way around the base. 

After sizing your coil to your base, lift the coil from your base. In a small cup, mix a small amount of  clay and quite a bit of water to make a wet, smooth mixture called slip. Then after set it aside for later use. To score, you will scratch the areas were you will be connecting the coils to the base. Make sure you place the slip on on top of the scoring. Place your coil to the base and knit them together. Also this is putting the two peices together. Lastly, to make it look good, you smooth the coils so no bumps are visible.

Leatherhard is the state that your project is in when there is some moisture, but not to much. They clay should not be too muchy or too hard. Leatherhard is the right amount of moisture to clean up and smooth your project. Your project should be somewhat firm in the leatherhard state. It is almost ready to be fired in the kiln after it dries out more!

Bisquare fire is the term used to describe a clay project in the process of being fired in the kiln. Bisquare firing uses temperatures up to 1940 degrees in the kiln.

Sanding is the process if using a strip of sand paper to smooth out any uneven parts of your project before glazing begins. Sanding may take a while depending on how much your project you need to sand. Sanding is like smoothing your project after it has been fired in the kiln.

When your project goes through the kiln you always have to make sure you rinse it. If you don't rinse, the glaze you put on it will not turn out the right colors.

Glazing is the most fun part of all. You can be the most unique and choose any colors you want to put on your project. There are many different glazes to choose from. Some include regular solid colors, and others add speckles of multiple colors and even add textures.

Glaze fire exists when you are finished glazing your project and is ready to be placed in the kiln to fire. Temperatures in the kiln reach up to 1950 degrees during the glaze fire process.

The Finished Project!
