DemiJohn Bottle Value Guide

These 19th-century French hand-blown glass vessels, famously known as 'Dame-Jeanne' bottles, are prized for their organic shapes and historical utility in transporting wine and spirits. Their collectible appeal lies in the unique legend of Queen Joanne of Naples and the artisanal imperfections inherent in antique glass production.

What affects the value of DemiJohn Bottle?

• Presence of original wicker casing or protective materials can significantly impact the bottle's market price.
• The specific shade and clarity of the glass, with rare colors commanding higher premiums than standard green.
• Overall condition, specifically the absence of cracks or heavy clouding from mineral deposits.
• Size and volume, as larger carboys are often more desirable for floor-standing interior design displays.

How to Identify DemiJohn Bottle?

• Look for a 'pontil mark' on the bottom, a rough scar where the glassblower's rod was detached.
• Identify hand-blown characteristics such as asymmetrical shapes and small air bubbles (seeds) trapped within the glass.
• Check for a thick, uneven rim or 'lip' at the top of the neck, which is typical of 19th-century manufacturing.
• Examine the glass for a slight green or amber tint, common in French utilitarian glass from this era.

History of DemiJohn Bottle

DemiJohn bottles, also known as carboys, have a rich history dating back centuries. They were originally used for transporting and storing wine, spirits, and other liquids. The term 'demijohn' is believed to have originated from the French 'dame-jeanne,' meaning 'Lady Jane,' referring to a popular legend of Queen Joanne of Naples who, seeking shelter from a storm, ordered a glassmaker to create a bottle to her specifications. The resulting large bottle was so well-received that it was named in her honor. These bottles were often encased in wicker or other protective materials for transport.
