National Clay Week – June 13-19, 2025

National Clay Week is celebrated from June 13 to 19 every year in the U.S. During this week, the pottery and ceramics communities celebrate the multipurpose use of clay. People attend lectures, watch demos, talk to vendors, and sign up for pottery classes. The annual National Council on Education for the Ceramic Arts (N.C.E.C.A.) conference is also held this week. National Clay Week also raises awareness of educational and professional opportunities related to pottery and ceramics. The week also celebrates the beautiful artifacts made with clay — objects that have monetary, cultural, and artistic value. There’s also a focus on how material possessions are important to us and the values they convey.

History of National Clay Week

National Clay Week has been observed every year since 1950 but the art of pottery is much older than that. Pottery might be the oldest human invention — it’s been around since before the Neolithic period. But why did humans choose clay to make all pottery? That is because clay has two important properties that make it an ideal material — clay can be molded into any shape we desire and, when it is baked, it becomes virtually indestructible and cannot be destroyed by any organic substances. Pots made of clay were used by early humans to store water and grains.

The first earthenware pottery was made more than 9,000 years ago and is in use even today. The color of the artifact depends on the type of clay used but they are often decorated by adding embellishments, embossments, or adding layers of paints. Earthenware pottery has also become a medium of art — artists have painted on them for centuries and they have become important relics of art, history, and culture.

Another form of creation made from clay is ceramics. Some ceramics are made with kaolin or white china clay. As compared to earthenware pottery, ceramics is a fairly new invention. In medieval times, ceramics from China made their way to Europe. They became prized possessions and were displayed at the house of the very rich for their intricate designs. Another form of ceramics, bone china, is easier to manufacture. It is strong, does not chip easily, and is very popular as dinnerware material in Europe.
