What does a network of interconnecting jagged lines in a hard fired ceramic likely indicate?

• A. Contamination during firing
• B. Thermal shock
• C. Surface porosity
• D. Inadequate glazing

Answer: (B)

A network of interconnecting jagged lines in hard fired ceramics is indicative of thermal shock. When ceramics undergo rapid temperature changes, they can experience differential expansion and contraction, leading to stresses within the material. If these stresses exceed the material's strength, cracks can develop, resulting in a pattern that resembles jagged lines. This phenomenon showcases that the material has been subjected to conditions that caused it to expand or contract unevenly, ultimately compromising its integrity. Understanding the implications of thermal shock in ceramic materials is crucial, as it can directly impact performance, durability, and suitability for various applications. The presence of such jagged lines may serve as a clear visual cue for assessing the quality and reliability of the ceramic product.
