Rippled glass

[1] Louis Comfort Tiffany made use of such textured glass to represent, for example, water or leaf veins.

A sheet is formed from molten glass with a roller that spins on itself, while travelling forward.

Normally the roller spins at the same speed as its own forward motion, and the resulting sheet has a smooth surface.

In the manufacture of rippled glass, the roller spins faster than its own forward motion.

In order to cut rippled glass, the sheet may be scored on the smoother side with a carbide glass cutter and broken at the score line with breaker-grozier pliers.
