What is the purpose of glazing in ceramics?

To fire clay at low temperature
To achieve a smooth, shiny surface and waterproofing
To create a porous material
To shape the clay into specific forms

The correct answer is: To achieve a smooth, shiny surface and waterproofing

Glazing in ceramics serves the important function of achieving a smooth, shiny surface and providing waterproofing to the clay body. When a glaze is applied to ceramics and subsequently fired in a kiln, it undergoes a chemical transformation that not only beautifies the surface but also forms a glass-like coating. This coating is essential for making ceramic items functional, as it prevents liquids from seeping into the porous clay. A well-applied glaze enhances the aesthetic appeal of the piece, offering a variety of colors and finishes, while also ensuring that the pottery can hold liquids without becoming damaged or degraded over time. This dual purpose of aesthetics and functionality is central to the practice of glazing in ceramics.
