This article continues our exploration of antique French glassware.
These objects were once simple tools of the kitchen and cellar, used daily in French households. Today they survive as beautiful reminders of traditional craftsmanship, their small imperfections revealing the hands that created them.
Among the most distinctive examples are hand-blown truffle and cornichon jars.
Tall, elegant, and subtly irregular, these jars once held some of the most prized ingredients of the French pantry. Today they are collected not only for their history but also for their sculptural beauty.

French Antique Truffle Jars and Cornichon Jars
A Brief History
During the nineteenth and early twentieth centuries, glass jars played an important role in preserving food in French kitchens.
Tall glass jars were often used to store truffles, pickled cornichons, preserved vegetables, and other delicacies. Their narrow form helped keep contents submerged in brine or liquid while allowing them to be easily removed when needed.
Each jar was blown individually by a glassmaker.
Working quickly with molten glass gathered on the end of a pipe, the glassblower inflated and shaped the vessel before finishing the rim and attaching a pontil rod to the base.
The result was a functional container that also carried the subtle marks of handmade production.
Recognizing Authentic Hand-Blown Jars
Collectors often look for several details that reveal traditional glassmaking.
Rolled or Applied Rims
Most antique jars feature a rolled or applied rim at the opening. This reinforcement strengthened the mouth of the jar while leaving slight irregularities that reveal hand finishing.
Bubbles in the Glass
Tiny air bubbles trapped within the glass are one of the most recognizable features of hand-blown jars.
In France, collectors sometimes refer to these bubbles as soufflures, a term associated with verre soufflé, or blown glass.
Rather than defects, these bubbles catch the light beautifully and reveal the handmade nature of the vessel.
Pontil Marks
The base of many antique jars shows a rough circular scar left by the pontil rod used during the blowing process.
This pontil mark is often one of the strongest signals of early glassmaking.
Subtle Irregularities
Because each jar was shaped by hand, slight asymmetry is common. The walls may vary in thickness, and the body may lean slightly to one side.
These variations are part of the character collectors appreciate.
Large Jars and Small Jars
Tall jars often attract attention because of their dramatic presence.
However, smaller jars are frequently harder to find.
Many of the larger jars were used repeatedly in kitchens or cellars and were easier to repurpose over time. Smaller jars were often more fragile and fewer survived.
For collectors, combining sizes creates a beautiful display. Larger jars provide visual presence, while smaller jars add refinement and variety.
Why These Jars Are Rare
These jars were never meant to survive for centuries.
Glass containers used in kitchens were constantly handled, washed, and moved.
Many inevitably broke during everyday use.
As industrial glass production replaced traditional glassblowing in the early twentieth century, the handmade versions gradually disappeared.
The jars that remain today are survivors of that earlier era of glassmaking.
How were truffle jars sealed
Unlike modern storage containers, truffle jars were rarely sealed with tight-fitting lids.
Fresh truffles need a small amount of airflow to prevent spoilage, so the jars were typically covered with fabric or parchment and tied with twine around the neck of the jar.
This simple method protected the contents while still allowing the truffles to breathe.
This is one reason many antique truffle jars have wide, slightly flared rims. The shape made it easy to secure cloth over the opening with string.
Today, collectors sometimes recreate this look when displaying the jars, using linen or parchment tied loosely around the neck as a nod to their original purpose.
Pro Tip: Checking Glass for Chips and Cracks
When I pick up a truffle or cornichon jar at a brocante or antique market, the first thing I do is run my finger slowly around the rim and along the base.
Small chips can be difficult to see, especially when the glass is dusty or has spent years sitting on a shelf. Running a finger along the edge makes them immediately noticeable.
The next step is to hold the jar up toward the sun or a strong light source. Light passing through the glass makes it much easier to detect cracks or structural weaknesses that may otherwise be invisible.
Many antique jars also contain large bubbles in the glass. These are part of the blowing process and are sometimes called soufflures in French. When viewed quickly, a large bubble can occasionally look like a crack running through the glass. A closer look usually reveals that it is simply an air pocket trapped during the blowing process rather than damage.
Because these jars were everyday kitchen vessels, it is common to find them dusty or slightly cloudy when they appear at markets. A careful inspection under good light is often the best way to understand the true condition of the piece.
Displaying Antique Truffle and Cornichon Jars
One of the reasons collectors value these jars so highly is their versatility in interior spaces.
A single jar placed on a shelf can become a quiet focal point. A group arranged together creates variation in height and tone, particularly when the glass ranges from olive green to smoky gray or soft amber.
Placed near natural light, the bubbles and subtle swirls within the glass become more visible, giving the jar a sense of movement and depth.
Unlike pottery, which feels grounded and earthy, antique glass interacts constantly with light.
Pairing With Other French Antiques
These jars look especially beautiful when displayed with other traditional kitchen antiques.
Placed beside confit pots or cruche pitchers, the warm terracotta contrasts beautifully with the cool transparency of glass. Antique cutting boards or aged wooden utensils introduce texture beneath the smooth surface of the jars.
Copper cookware adds warmth and reflection, while smaller apothecary bottles can create layered displays of historic glass.
Together these objects recreate the feeling of an old French pantry or kitchen.
A Note From the Markets of Provence
After visiting brocantes and antique markets across southern France, one thing becomes clear.
Many of these jars survived purely by chance.
Some were tucked away in old kitchens or cellar shelves for decades. Others appeared in barns or storage rooms long after their original purpose was forgotten.
When they finally surface at a market table, their imperfections reveal their history.
Pick one up and you immediately notice the bubbles in the glass, the slightly uneven rim, and the pontil mark beneath the base.
These jars were never intended to become collectibles. They were simply practical containers made by glassblowers who likely never imagined their work would still be admired generations later.
FAQ: Antique French Truffle and Cornichon Jars
How old are antique French truffle and cornichon jars?
Most authentic truffle and cornichon jars found today date from the mid to late 19th century, roughly between 1850 and 1900.
During this period, glass was still commonly hand blown, which is why these jars show bubbles in the glass, irregular rims, and pontil marks on the base.
What were truffle jars used for?
These jars were traditionally used to store truffles and preserved foods in French kitchens.
How can you tell if a jar is hand-blown?
Look for bubbles in the glass, irregular rims, and pontil marks on the base.
Why are smaller jars more rare?
Smaller jars were more fragile and fewer survived over time.
Are antique jars valuable?
Their value depends on size, condition, and rarity, but collectors appreciate them primarily for their craftsmanship and historic character.
What is the difference between a truffle jar and a cornichon jar?
The shapes are very similar and were often made by the same glassmakers.
Truffle jars were used to store fresh truffles and were typically covered with fabric or parchment tied with twine so the contents could breathe.
Cornichon jars held pickled gherkins stored in brine and were often slightly taller and narrower to keep the vegetables submerged.
