Question

Arrange the following pottering according to their required temperature from High temperature to low temperature. A. Raku
B. Porcelain
C. Stone ware
D. Terracotta
E. Earthenware

• A. A, D, E, C, B
• B. B, C, E, D, A
• C. B, C, D, E, A
• D. B, C, A, D, E

Hint:

Logic Tip: Porcelain is always the hottest. Raku is always the coolest (pulled out red hot). Finding B first and A last instantly isolates Option 2.

Answer 1

The Correct Option is B

Concept:
Different clay bodies are engineered to mature and vitrify at very specific kiln temperatures based on their purity and flux content.
•

Step 1:
Porcelain (B) is extremely pure, consisting mostly of refractory kaolin and silica. It requires massive heat (often Cone 10 to Cone 13+, or $1300^{\circ}\text{C}+$) to become translucent and vitrified.
•

Step 2:
Stone ware (C) is a robust, high-fire body that matures just below porcelain, typically between Cone 5 and Cone 10 ($1200^{\circ}\text{C}$ to $1280^{\circ}\text{C}$).
•

Step 3:
Earthenware (E) is a general category of low-fire clay (Cone 06 to Cone 04, around $1000^{\circ}\text{C}$). Terracotta (D) is a specific, highly porous, iron-rich type of earthenware often fired at the lower end of the earthenware spectrum.
•

Step 4:
Raku (A) is a fast-firing technique where pots are pulled out of the kiln as soon as the glaze melts, often at incredibly low temperatures compared to standard maturity firings (Cone 010 to Cone 06, around $900^{\circ}\text{C}$ to $1000^{\circ}\text{C}$).
•

Step 5:
Sorting from hottest to coolest gives: Porcelain (B), Stoneware (C), Earthenware (E), Terracotta (D), Raku (A). \[ \boxed{\text{(2) B, C, E, D, A}} \]
