The prime advantage of vacuum firing of porcelain is?

Vacuum firing of porcelain has been shown to significantly increase the strength of the material. This is because the vacuum firing process allows for a more complete and uniform distribution of the glaze and porcelain particles, resulting in a stronger bond between them. While the other options may also be benefits of vacuum firing, they do not provide the same level of improvement to the strength of the porcelain. Faster production time and decreased cost may be appealing, but they may sacrifice the quality and strength of the final product. Better color match may also be desirable, but it does not directly address the strength of the porcelain. Therefore, B Increased strength is the prime advantage of vacuum firing of porcelain.
