Few pieces of antique French glass command as much presence as the demijohn.
Tall, rounded, and often wrapped in wicker, these large glass vessels once served as practical storage containers in vineyards and rural homes across France. Today they have taken on a very different role. Their scale, color, and hand-blown character make them striking decorative objects in modern interiors.
What was once a working container has become a sculptural reminder of traditional French glassmaking.

The Antique French Demijohn or Dame Jeanne Bottle
What Is a Demijohn
Demijohns are large glass vessels historically used for storing and transporting liquids.
In France they are commonly called dame-jeannes, particularly when referring to the large round-bodied bottles. Smaller versions are sometimes referred to as bonbonnes.
These containers were used for wine, cider, olive oil, vinegar, and other liquids produced in rural households and vineyards.
Because they held large quantities, their thick glass bodies and wide shoulders helped protect the contents during transport and storage.
Although practical in purpose, their handmade production gave them forms that are both irregular and visually striking.
The Art of Creating a Demijohn
Authentic antique demijohns reveal the details of their creation.
The Rim
One of the details that surprises many people when they first handle an antique demijohn is the rim.
At first glance, the mouth of the bottle can look like broken glass. This is because the glassblower originally cut the vessel from the blowpipe, leaving a rough opening at the neck.
To reinforce the mouth and make it usable, the glassmaker then applied a band of molten glass around the rim. This ring of glass was shaped while still hot to create a stronger lip for pouring and sealing.
These applied lips are often slightly uneven, which is a normal result of hand finishing.
On some demijohns the lip is simple and rounded, while on others it may appear braided, folded, or decorative, creating a subtle spiral pattern around the neck.
Rather than being a flaw, this irregular rim is one of the clearest signs of traditional hand-blown glassmaking. It reveals the moment when the vessel was finished by the artisan.
Bubbles in the Glass
Small air bubbles are one of the most recognizable signs of hand-blown glass.
In France these bubbles are sometimes referred to as soufflures, reflecting the blowing process used to shape the glass.
Rather than being defects, these bubbles catch light beautifully and reveal the handmade nature of the vessel.
Pontil Marks
Many older demijohns show evidence of the pontil rod used during production. This rod helped hold the bottle while the neck was finished, often leaving a scar or irregularity at the base.
Mold Lines
Earlier demijohns were often free-blown, meaning they were shaped entirely by hand without molds.
Later examples sometimes show faint vertical seams where molds were introduced to create more consistent shapes during the late nineteenth and early twentieth centuries.
Color and Glass Variation
Antique demijohns appear in a range of colors.
Most examples are found in shades of deep forest green or olive green. These colors resulted from the natural minerals present in the sand used during glassmaking.
Occasionally lighter tones appear, including pale aqua or smoky gray.
The glass may show ripples, swirls, and variations in thickness where the molten material shifted during the blowing process. These irregularities give each vessel its own character.
Corks and Closures
Historically, demijohns were sealed with cork stoppers.
These corks were sometimes wrapped with cloth or sealed with wax to protect the contents during storage. Because cork deteriorates over time, most surviving demijohns no longer retain their original closures.
The wide rims and thick necks remain as reminders of their working past.
Wicker Carriers
Many demijohns were originally placed in wicker or wooden carriers.
These baskets protected the glass during transport and allowed the heavy vessels to be handled more easily. Over time, however, the wicker often deteriorated or developed mold.
For this reason many collectors focus primarily on the glass vessel itself rather than the carrier.
The demijohn remains the true collectible.
Pro Tip: Inspecting Demijohns
Most demijohns found at brocantes and antique markets are extremely dirty. Years of cellar dust, residue, and storage grime can make it difficult to see the true condition of the glass.
One of the best ways to inspect them is to hold the vessel up toward the sun or a strong light source. Light passing through the glass will often reveal hairline cracks that are otherwise invisible.
Rather than only checking the rim and base for chips, it is also helpful to run the palm of your hand gently across the entire surface of the glass. Small chips or rough spots on the body of the demijohn can sometimes be difficult to see but are immediately noticeable to the touch.
Another quick authenticity clue is the rim itself. If the mouth of the bottle looks perfectly smooth and machine-finished, the piece is likely modern. Older demijohns usually have irregular applied lips where molten glass was added to strengthen the neck.
Why Demijohns Are So Appealing Today
Demijohns combine scale with craftsmanship.
Large examples create dramatic focal points in a room, while smaller examples are often prized by collectors because they are easier to display.
Every demijohn carries slight irregularities in shape, color, and glass thickness that reflect the hand of the glassmaker.
These imperfections are part of what gives antique glass its charm.
Displaying Demijohns in the Home
Demijohns integrate easily into a variety of interior spaces.
Placed on the floor beside a console or cabinet, a single demijohn becomes a sculptural object. Positioned near a window, the glass catches natural light and reveals bubbles and subtle variations in the glass.
Some collectors enjoy grouping several demijohns together in different sizes and shades, creating a layered display of historic glass.
Their transparency and scale allow them to stand out without overwhelming a room.
Cleaning Antique Demijohns
Cleaning the inside of a demijohn can be challenging because of its narrow neck and large interior. All the demijohns we send are thoroughly cleaned, but if you've bought one at a vide-grenier or brocante, this section will help.
One effective method is to place a small piece of fine steel wool inside the vessel, then use a strong magnet wrapped in cloth on the outside of the glass. The magnet attracts the steel wool through the glass, allowing you to move it around the interior surface to remove residue and buildup.
By slowly guiding the magnet along the outside of the bottle, the steel wool follows along the inside, making it possible to clean areas that would otherwise be difficult to reach.
Warm water and mild soap are usually enough to loosen most dirt or residue. Once cleaned, the natural bubbles, ripples, and variations in the glass become much more visible.
A small note of caution: always use very fine steel wool and make sure the magnet is wrapped in cloth. A bare magnet can scratch the surface of the glass as it moves along the outside of the bottle.
Pairing With Other French Antiques
Demijohns pair beautifully with other traditional kitchen and cellar objects.
Placed beside antique wine bottles or wine glasses, they evoke the history of the vineyard. Copper cookware adds warmth beside the cool green glass. Wooden cutting boards or antique tables ground the display with rustic texture.
These combinations recreate the atmosphere of an old French kitchen or wine cellar.
A Note From the Markets of Provence
At brocantes and antique markets across southern France, demijohns are among the objects that immediately draw attention.
Some appear stacked beneath tables or resting beside old furniture. Others emerge from barns or cellars where they sat unused for decades.
When you lift one, you quickly notice the bubbles in the glass, the uneven rim, and the subtle irregularities in the body.
These vessels were never meant to become decorative objects. They were simply containers made quickly and practically by glassblowers who likely never imagined they would still be admired generations later.
Yet today they remain some of the most recognizable forms of antique French glass.
