What's the difference between enamel and latex?

Enamel


Definition:

  • (v. t.) A variety of glass, used in ornament, to cover a surface, as of metal or pottery, and admitting of after decoration in color, or used itself for inlaying or application in varied colors.

  • (v. t.) To form a glossy surface like enamel upon; as, to enamel card paper; to enamel leather or cloth.
  • (v. t.) To disguise with cosmetics, as a woman's complexion.
  • (v. i.) To practice the art of enameling.
  • (a.) Relating to the art of enameling; as, enamel painting.

Latex


Definition:

  • (n.) A milky or colored juice in certain plants in cavities (called latex cells or latex tubes). It contains the peculiar principles of the plants, whether aromatic, bitter, or acid, and in many instances yields caoutchouc upon coagulation.

Example Sentences:
