Which ceramic body is typically fired at the highest temperatures and is white and translucent?

• A. Stoneware
• B. Earthenware
• C. Kaolin
• D. Porcelain

Answer: (D)

Porcelain is the ceramic body fired at the highest temperatures and known for its whiteness and translucency. It’s made mainly from kaolin, along with silica and feldspar, and the intense firing causes a dense, glassy matrix to form. That dense vitrification reduces porosity and lets thin sections transmit light, giving the characteristic translucence, while the low iron content helps keep the color very white. Other common bodies don’t reach this combination: stoneware is fired hot but remains opaque and more stone-like; earthenware is fired at lower temperatures and stays porous unless glazed. Kaolin is a mineral used to make porcelain rather than a finished fired body on its own. So porcelain best fits being fired at the highest temperatures and appearing white and translucent.
