Which term refers to applying color to unfired porcelain before glazing and firing?

• A. Underglaze
• B. Rotunda
• C. Oculus
• D. Concrete

Answer: (A)

Underglaze is color applied to porcelain while the surface is still unfired (leather-hard or bone-dry), before a glaze is added and the piece is fired. When the glaze is later brushed on and the piece is fired, the color sits beneath the glassy glaze, giving crisp, controlled decoration that stays protected by the glaze. This technique is common for porcelain because it allows fine lines and consistent color under the final surface. The other terms refer to architectural concepts or materials and aren’t related to decorating porcelain.
