Ripple
The items shown are the "Novelty Vases". They are quite scarce
to find in Opalescent colors today. This pattern is most often found
in Carnival Glass and is often confused with another pattern called "Ribbed Spiral".
Here's an easy way to tell them apart. The "Ripple" pattern has seperate rings.
"Ribbed Spiral" has one ring that spirals from the bottom to the top. (See Ribbed Spiral).
