Final answer:
The three main components of a ceramic glaze are silica, flux, and alumina.
Step-by-step explanation:
The three main components of a ceramic glaze are silica, flux, and alumina. Silica is the primary component and acts as a glass former, providing structure and transparency to the glaze. Flux helps lower the melting point of the glaze and promotes its ability to adhere to the ceramic surface. Alumina acts as a stabilizer, preventing the glaze from running or dripping during firing.
