Description & Authentication

This bowl is a fine example of early American Carnival Glass, characterized by its pressed glass base and iridized surface. The deep amethyst base color is among the most collectible, as it was more difficult and expensive to produce than the more common marigold. When held to light, the purple glass shows through the vibrant iridescent coating — a hallmark of true early production.

The radial swirl design on the interior appears to be a variant of a “swirl” or “flower petal” motif, often used by several manufacturers during the golden era of Carnival glass production. The exterior starburst and scalloped raysare highly decorative and point toward production by:

• Northwood Glass Company
• Dugan Glass Company
• Imperial Glass Co.

Among these, Dugan and Northwood were particularly known for purple bases with high iridescence and complex ruffled shapes.

The base shows a cut-style starburst design with alternating points — common in patterns like “Many Stars” or “Vintage,” but without a known pressed pattern name visible, this could be a lesser-known variant or a mold variation used by smaller operations or during later runs.

Historical Context

Carnival glass was introduced in the early 1900s as a more affordable alternative to expensive Tiffany or Steuben iridescent glass. It was distributed through dime stores, premiums, or given away at fairs — hence the name “carnival glass.” Purple (amethyst) examples were prized and often used for more decorative or elaborate molds.

Current Market Value (as of mid-2025)

• Retail/Collector Value: $60 – $125 USD
• Insurance Replacement Value: $150 USD
• Auction/Resale Estimate: $40 – $80 USD

Your piece is especially desirable due to its deep amethyst base, strong iridescence, excellent condition, and ruffled form. While smaller than some centerpiece bowls, its size makes it ideal for collectors of miniatures or display sets.

Conclusion & Recommendations

This bowl is a well-preserved early 20th-century example of American carnival glass, most likely produced by a recognized manufacturer but without a visible maker’s mark. Its combination of rich base color, crisp pattern, and radiant luster place it in the mid-to-high tier of collectible carnival pieces.

Recommendation: If desired, you could consult a carnival glass specialist (such as via the Carnival Glass Society or local appraisal fairs) for a more precise pattern/maker ID. However, based on your documentation and images, its value and collectibility are solidly established.
