What's the difference between enamel and erosion?

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. i.) To practice the art of enameling.
  • (a.) Relating to the art of enameling; as, enamel painting.

Erosion


Definition:

  • (n.) The act or operation of eroding or eating away.
