Ăn'a-clăs'tic, a.
a. [Gr. ἀνακλῶ, to bend back and break; of light, to reflect; from ἀνά, back, and κλάω, to break; κλάσις, a breaking.]
- (Opt.) Produced by the refraction of light, as seen through water; as, anaclastic curves. Hutton.
- Flexible, as certain glasses or phials, with flat bellies, like inverted tunnels, and with very thin, convex bottoms. By drawing out a little air, the bottom springs into a concave form with a smart crack; and by breathing or blowing into them, the bottom, with a like noise, springs into its former convex form.
