Vintage glass
Carnival glass
Iridescent pressed glass, early 1900s
Machine-pressed glass given a metallic iridescent spray, sold cheaply in the early 20th century and later associated with carnival prizes. Color names (marigold, amethyst) describe the base glass plus the iridescent treatment.
Visible identification features
- Pressed pattern (ribs, grapes, geometric) visible under the shimmer
- Iridescent marigold, purple, green, or blue surface — not a painted stain that wipes off
- Often bowls, vases, and plates; mold lines possible
What the photo can and cannot prove
Iridescence plus a pressed pattern supports carnival-type glass. Maker (Northwood, Fenton, Imperial, etc.) usually needs a mark or a well-known pattern — not a guess from color alone.
Lookalikes
- Depression glass
Depression glass is typically transparent colored glass without the metallic carnival spray. Carnival looks “oily” or rainbowed.
Next steps
- Photograph the interior, the exterior, and the base for a maker’s mark.
- Not an appraisal. Pattern + maker + damage drive interest; shine in a photo does not.
