How is viscosity affected in enamel during the glazing process?

During the glazing process, viscosity in enamel significantly changes as the material is subjected to heat. In this high-temperature environment, the enamel melts and transforms into a liquid state, which allows it to flow and adhere smoothly onto the surface of the object being glazed. This transition is crucial because it enables the enamel to settle into an even layer and form a glass-like finish upon cooling.

When the enamel reaches the appropriate temperature, its viscosity decreases, facilitating the coating process. Once it cools down, the liquid enamel hardens, forming a durable and attractive surface. This property of changing to a liquid form when heated is essential for achieving the desired aesthetic and functional qualities in the final glazed piece.
