Pottery is a form of art that involves creating objects, such as vases, bowls, and figurines, from clay that has been fired in a kiln. When clay is fired, it undergoes a process called vitrification, in which the water in the clay is removed and the clay becomes hard and durable.
There are two main types of pottery: earthenware and stoneware. Earthenware is fired at a lower temperature, typically around 1000-1200 degrees Fahrenheit, and it is more porous and prone to cracking. Stoneware, on the other hand, is fired at a higher temperature, typically around 1800-2200 degrees Fahrenheit, and it is less porous and more durable.
When clay is fired once, it is typically classified as earthenware. Earthenware is often used for functional objects, such as dishes and pots, because it is relatively inexpensive and easy to work with. However, earthenware can also be used for decorative purposes, and it can be painted or decorated with glazes or other materials.
Overall, earthenware that has been fired once is a versatile and affordable material that can be used to create a wide range of objects, from functional dishes to decorative sculptures.
