Question:
\(\ldots\ldots\ldots\ldots\ldots\) contains high percentage of Feldspar.
\(\ldots\ldots\ldots\ldots\ldots\) contains high percentage of Feldspar.
Show Hint
Dental porcelain is feldspathic porcelain because it contains a high percentage of feldspar.

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Feldspar is an important fluxing material in porcelain bodies.
It helps in vitrification during firing.
Different types of porcelains contain different proportions of clay, quartz, and feldspar.
Dental porcelain requires good translucency, smooth surface, and proper fusion behavior.
For these properties, dental porcelain contains a high percentage of feldspar.
Feldspar provides a glassy phase after firing.
This glassy phase gives dental porcelain its translucency and aesthetic appearance.
Soft porcelain and hard porcelain also contain feldspar, but dental porcelain is especially feldspathic in nature.
Therefore, the porcelain containing a high percentage of feldspar is:
\[
\text{Dental porcelain}.
\]
