What Is Iridescent Glass Lamp Shade Worth?

The typical price range for Iridescent Glass Lamp Shade is $70 - $85 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

How to Identify Iridescent Glass Lamp Shade?

• Look for a warm, luminous glow and a rainbow-like surface shimmer created by metallic salt applications.
• Examine the top for a characteristic ruffled or crimped edge typical of early 20th-century American glasswork.
• Check for signs of hand-blown manufacturing, such as slight variations in the glass thickness or a pontil mark.
• Verify the era by ensuring the iridescent sheen is integrated into the glass rather than a modern spray-on coating.

History of Iridescent Glass Lamp Shade

Iridescent glass, known for its rainbow-like surface shimmer, gained immense popularity during the Art Nouveau period, particularly from the late 19th to early 20th centuries. This effect was often achieved by applying metallic salts to hot glass, a technique perfected by glassmakers like Louis Comfort Tiffany. These shades were commonly used on oil lamps and electric lamps, adding a touch of elegance and whimsy to home lighting.
