Vintage Jeanette Glass iridescent Marigold Carnival Glass sherbet or champagne glass.

Vintage Jeanette Glass iridescent Marigold Carnival Glass sherbet or champagne glass. This type of glass was popular in the early 20th century and is known for its iridescent, rainbow-like sheen, which is created by spraying metallic salts onto the glass while it is still hot from the mold. The glass in the image features a ribbed pattern and a footed base, typical of sherbet or champagne glasses from that era. The specific pattern is likely the "Iris and Herringbone" pattern. Jeanette Glass Company produced this type of glass from the 1920s to the 1930s, making this piece a collectible item.
