What kind of ceramic ware is made from porous clay and fired at low heat?

1. Stoneware

2. Porcelain

3. Earthenware

4. Bone china

The correct answer is: Earthenware

The correct answer is earthenware, which is a type of ceramic ware created from natural clay that is known to be porous. It is fired at relatively low temperatures, typically ranging between 1,830°F and 2,400°F (1,000°C to 1,300°C). This firing process gives earthenware its characteristic soft and porous quality, allowing it to be more easily molded and decorated. Earthenware is often used for pottery, tiles, and various decorative items. Because of its porous nature, it is typically glazed to make it more water-resistant and durable for practical uses. It is important in various cultural traditions and craft practices due to its accessibility and versatility. In contrast, stoneware, porcelain, and bone china are all made from different types of clay and processed at higher temperatures. Stoneware is denser and less porous, while porcelain is a refined clay body that is fired at high temperatures, resulting in a non-porous and vitreous finish. Bone china, known for its delicate structure and strength, also goes through higher firing processes and includes bone ash in its composition, allowing it to be thin yet strong. Thus, earthenware distinctly stands out due to its low firing process and porosity.
