Which of the following is NOT a type of ceramic clay?

Brick clay is not considered a type of ceramic clay in the same category as kaolin, porcelain, and stoneware. While brick clay is used in the production of bricks and is characterized by its ability to withstand high temperatures and maintain structural integrity, it is generally more coarse and has different properties compared to the finer, more refined types of clay used in ceramics.

Kaolin, porcelain, and stoneware are all types of clay that are specifically utilized for creating ceramic artworks or functional items. Kaolin, often referred to as "china clay," is known for its high purity and is a key ingredient in porcelain. Porcelain itself is a type of ceramic that is fired at high temperatures, resulting in a translucent quality and strength. Stoneware is another ceramic type that is fired at high temperatures but has a denser structure and is often used for making durable pottery. Each of these clays has unique characteristics that make them suitable for different applications in ceramic artistry and pottery.
