Question:
Dental Porcelain contains high percentage of
Dental Porcelain contains high percentage of
Show Hint
Dental porcelain is feldspar-rich because feldspar helps in producing a glassy and translucent appearance.

The Correct Option is A
Solution and Explanation
Concept:
Dental porcelain is a special type of porcelain used for dental crowns, bridges, and artificial teeth. It should have good translucency, strength, and appearance similar to natural teeth.
Step 1: Dental porcelain mainly contains feldspar as the major constituent.
Step 2: Feldspar melts during firing and forms a glassy phase.
Step 3: This glassy phase gives translucency and smooth appearance to dental porcelain.
Step 4: Quartz provides strength and dimensional stability, but it is not the highest percentage component.
Step 5: Clay is used in small amounts because too much clay reduces translucency. Therefore, dental porcelain contains high percentage of: \[ \boxed{\text{Feldspar}} \]
