  • (20) The artist covered every inch of the steps in front of his house in tiles, ceramics and mirrors – originally in the green, yellow, blue and white of the Brazilian flag, later adding tiles in other colours brought by visitors.

Porcelain


Definition:

  • (n.) Purslain.
  • (n.) A fine translucent or semitransculent kind of earthenware, made first in China and Japan, but now also in Europe and America; -- called also China, or China ware.

Example Sentences:

  • (1) The colors of mixtures of dental opaque porcelains and modifiers were measured with use of the CIE L*a*b* uniform color space.

  • (10) Porcelain veneer restorations including preparations, impression materials, cast materials, refractory casts, handling of porcelain, the try-in, and the final luting are discussed.
  • (11) Clinical observations of porcelain restorations lead to the hypothesis that certain substructures tend to produce crowns with a lower than expected Value (brightness).
