Introductory courses in ceramics are intended to give a basic yet broad understanding of handbuilding techniques with clay as the vehicle for self expression. As the student advances, there is a freedom in technique as well as in choice of clay body and firing temperature. Specific courses on throwing, moldmaking and clay and glaze technology are part of the curriculum. Advanced courses focus on self-generated projects selected by the student and guided by the instructor and give students the opportunity to load and fire kilns.

Of all the kinds of artifacts which may be found at archaeological sites, ceramics is surely one of the most important. Ceramic artifacts are extremely durable, and may last tens of thousands of years virtually unchanged from the date of manufacture. And, ceramic artifacts, unlike stone tools, are completely person-made, shaped of clay and purposely fired.

Crazes are small cracks in the glazing of ceramics. They are caused by many factors, such as a different thermal expansion rate between the glaze and the clay, glaze ingredients, and the firing process. Whenever possible, crazed (and cracked surface) ceramics should be generally avoided for food contact, as the cracks can harbor colonies of bacteria; using a bit of chlorine bleach or lemon to clean the cracks will help to rid bacteria.
