Anaclastic \An`a*clas"tic\, a. [Gr. ? to bend back and break; to
reflect (light); ? + ? to break.]
1. (Opt.) Produced by the refraction of light, as seen
through water; as, anaclastic curves.
[1913 Webster]
2. Springing back, as the bottom of an anaclastic glass.
[1913 Webster]
{Anaclastic glass}, a glass or phial, shaped like an inverted
funnel, and with a very thin convex bottom. By sucking out
a little air, the bottom springs into a concave form with
a smart crack; and by breathing or blowing gently into the
orifice, the bottom, with a like noise, springs into its
former convex form.
