Hand-Blown Cobalt Blue Vase Value Guide

This American-made cobalt blue vase represents the peak of early 20th-century glassmaking, where functional household items were elevated to decorative art. Its intense hue, achieved through the precise addition of cobalt oxide, makes it a standout piece for collectors of period glassware.

What Is Hand-Blown Cobalt Blue Vase Worth?

The typical price range for Hand-Blown Cobalt Blue Vase is $70 - $90 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Overall condition, specifically the absence of 'sick glass' cloudiness or internal mineral deposits.
• The presence of a well-defined, polished pontil scar which can increase desirability among glass enthusiasts.
• Structural integrity of the flared rim, as chips or flea bites significantly reduce the $70-$90 valuation.
• Clarity and depth of the cobalt blue pigment, with more vibrant examples commanding the higher end of the price range.

How to Identify Hand-Blown Cobalt Blue Vase?

• Look for a pontil mark on the bottom of the base, indicating the piece was hand-blown rather than mold-made.
• Inspect the flared rim for slight irregularities in thickness characteristic of manual shaping techniques.
• Verify the deep, consistent cobalt saturation which should be uniform throughout the glass body.
• Check for small, trapped air bubbles or 'seeds' within the glass, common in early 1900s production.
