The basic process of how clay pots are made hasn’t really changed much for a few thousand years. So let’s take a look at how it happens
Before We Start
No lead in clay or glazes.
Different pots for different types of heat and cooking.
Forming the Pot
Most pottery made by studio potters and production is made by throwing on a potters wheel, hand-building by coils, slabs and other shapes, or by using a mold or hydraulic press.
Trimming, Drying and the First Firing
Once formed, the pot is partially dried to where it will hold its shape if handled. Typically the bottom is formed first, then handles and decorative trim is added.
The first firing is done after the pot is fully dried. It is called a bisque firing.
Glazing
Glazing is both an art and a science. Science, because most glazes are a combination of various clays and powdered rocks, combined with water.
Glazing is an art because the glaze may changer color and/or move from when it’s put on, and the potter tries to predict the end point. Wally used to call it, “setting up intentional accidents.”
Firing
The final firing (glaze firing), takes place when the glaze is fully dried. It can be done in an electric kiln, gas kiln or other fuel such as wood, or even some types of clay fired in a wood or brush fire.
