Antique Block Design Ruffled Opaline Blue Vase Or Celery Holder

No chips or cracks 5 x 4 inch This vase appears to be an example of late 19th or early 20th-century opalescent glass, a style popularized by American glassmakers such as Northwood and Jefferson. These companies were known for producing affordable, decorative glassware with distinctive opalescent rims and intricate molded patterns. The 'block' or 'beads and bark' pattern, as seen in the vase's grid-like design, was a common motif during this period.

Opalescent glass was created by adding chemical compounds to the molten glass, causing it to become translucent and milky white when cooled. This technique allowed manufacturers to produce glassware that mimicked the appearance of more expensive, hand-blown pieces. Today, these vases are collected for their historical significance and aesthetic appeal, representing a bygone era of American glass production.
