The clay is then briefly "wedged" by hand to establish a consistency in the raw materials and align the clay particles and remove any air left over from the pugging process. There are two types of wedging we use. .
Placing the fingers in position ready to lift the pot off. The index and second fingers of each hand are spread under and round the base on each side, spanning it as far as possible.
The pot should be lifted off by peeling from one side, not by rising the entire pot at once. Many pot are spoiled in the way they are lifted off. If the undercutting with the trimming tool has given a clear space at the base for the fingers to get righr under the pot. There should be no difficulty.
Excess water is removed from the bowl with a sponge which also smoothes the surface and contributes to the strength of the finished bowl when it is in your kitchen environment. For wheel throwing , once the clay is pugged and wedged it is centered on the wheel. This is a very critical step.
After the pot is completely dry it is ready to be bisque fired. This initial firing removes the physical and chemical water so that the piece can be glazed without returning to mud and breaking. The temperature we bisque at is approximately 1700 degrees Fahrenheit. Many potters prefer to bisque at a higher temperature as more impurities are forced from the clay.
The next stage in the creation of the pot is the application of glaze. Check the pot and remove any bumps or imperfections we see. We may use a 100 grit sandpaper or a kitchen paring knife edge to smooth surfaces. We then sponge the entire surface of the pot to remove any dust left from sanding to provide a clean surface for the glaze to adhere to.
