Question

What are the characteristics of the stoneware ceramic?

• A. Soft, porous and moist
• B. Hard, Fired and non porous
• C. Fired, porous and soft body
• D. Soft, porous and opaque body

Hint:

Ceramic properties are determined by firing temperature. Earthenware is low-fired and porous. Stoneware and Porcelain are high-fired, leading to vitrification, which makes them hard and non-porous.

Answer 1

The Correct Option is B

Step 1: Understand the properties of stoneware. Stoneware is a type of ceramic that is fired at a high temperature (typically between 1100°C and 1300°C). This high firing temperature causes the clay particles to fuse together in a process called vitrification.
Step 2: Relate vitrification to physical properties. Vitrification makes the ceramic body dense, hard, and non-porous (impermeable to water). Therefore, stoneware is characterized as being hard, fired, and non-porous. Options describing softness and porosity refer to lower-fired ceramics like earthenware or unfired clay.
