Chapter 9: Problem 4

State whether the following statements are true or false. Impervious nature of ceramics is the effect of glazing.

Short Answer

Expert verified
Explain your answer. Answer: Yes, the impervious nature of ceramics can be a result of glazing. Glazing creates a waterproof barrier on the surface of the ceramic, preventing water and other liquids from penetrating the material. However, some ceramic materials may be intrinsically impervious even without glazing, depending on their composition and structure.

Step by step solution

01

Understand the impervious nature of ceramics

The impervious nature of ceramics refers to their ability to be waterproof and not allow water or other liquids to pass through them. This property is essential for many practical applications of ceramics, such as tableware, tiles, and other household items.
02

Understand glazing

Glazing is a process in which a thin layer of glass-like material is applied to the surface of a ceramic object and then fired at high temperatures. The glaze can serve several purposes, such as improving the appearance of ceramics, adding decorative patterns, and making the ceramic object more resistant to wear, scratches, and stains. One significant effect of glazing on ceramics is making them more impervious by creating a waterproof barrier on the surface.
03

Evaluate the statement

The statement "Impervious nature of ceramics is the effect of glazing" is true. The impervious nature of ceramics can be enhanced by the application of glazing. The glaze forms a barrier that prevents water and other liquids from penetrating the ceramic material. However, it is essential to mention that some ceramic materials can be intrinsically impervious even without glazing, depending on their composition and structure.
