How do I identify air twist stems?

Air twists appear as delicate, elongated bubbles trapped inside the stem of a drinking glass, often drawn into a fine spiral. They reflect light differently than the surrounding clear metal. Examine the stem under good lighting to trace the continuous thread pattern running from the bowl down toward the foot.

How were jelly glasses used?
