This document discusses the properties of clay and how it changes when fired in a kiln. It asks what matter is, the physical properties of matter, whether clay is a solid, liquid or gas, the forces needed to change matter, how high heat in a kiln changes clay, if the changes can be reversed, how glazes differ from paints, and poses questions about clay.

Notas del editor
- Objects that take up space and have mass are called matter.
- Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others.
- The three states of matter are: solid, liquid, and gas.
- If energy is added (like increasing the temperature or increasing pressure) or if energy is taken away (like freezing something or decreasing pressure) you have created a physical change.
- heat
- Permanently vitrifies it.
