Vaseline Glass Bowl Value Guide

This 1930s Vaseline Glass Bowl from the United States is a prized example of uranium-infused decorative art. Its distinct yellow-green hue and remarkable luminescent properties, caused by uranium oxide, make it a standout piece for Depression-era glass collectors.

What affects the value of Vaseline Glass Bowl?

• The intensity of the glow under UV light, which indicates the concentration of uranium oxide used in the 1930s mixture.
• Physical condition, specifically the absence of 'flea bites,' chips, or cloudiness often found in antique glassware.
• The complexity of the pattern and the specific American manufacturer, as certain 1930s molds are rarer than others.
• Market demand for the $150-$200 price range, which is heavily influenced by the bowl's size and aesthetic appeal.

How to Identify Vaseline Glass Bowl?

• Verify the signature neon green glow by placing the bowl under a long-wave ultraviolet (UV) light source.
• Check for the characteristic oily, yellowish-green tint that resembles petroleum jelly in natural daylight.
• Examine the piece for 1930s American manufacturing marks or patterns consistent with the Depression glass era.
• Confirm the material is glass rather than modern plastic by checking for weight and cold-to-the-touch surface temperature.

History of Vaseline Glass Bowl

Vaseline glass, also known as uranium glass, gained popularity in the late 19th and early 20th centuries. Its characteristic glow is due to the small percentage of uranium oxide added to the glass mixture. Though its radioactivity is negligible, its unique luminescent properties made it highly sought after for decorative items.
