The art of free glassblowing: How a casa vitri object is created
When perfection is not the goal
In a world where machines produce thousands of identical wine glasses per hour, we have chosen a different path: Every casa vitri glass is created entirely by hand, without any mold, without a template, without a machine.
The result? Glasses that aren't perfect. And that's precisely the point.
What "freehand" really means
Perhaps you've seen wine glasses advertised as "mouth-blown." That sounds handcrafted, doesn't it? But the reality is often quite different: While most of these glasses are indeed created with a person's breath, they're made in a pre-made mold. The glass is blown into the mold, taking on its shape, and the result is a perfectly symmetrical product.
At casa vitri, we work differently. Our master glassblower, Eckhard Martin, or Ecki as we call him, shapes each glass exclusively with his hands, his breath, and gravity. No mold dictates how the bowl should look. No template determines the curve of the stem.
This is true freehand glassblowing. And very few people in the world can do that.
50 years of experience in every movement
Ecki has been a master glassblower since 1975. For over five decades he has perfected his craft, or rather: he has learned to dance with the unpredictability of the material.

Because glass has a will of its own. At over 1,000 degrees Celsius at the burner, it behaves like viscous honey. It flows, it drips, it follows gravity. And it is precisely at this moment, when the material is at its most vibrant, that the master must act.
"Every glass has a soul," says Ecki. "You just have to be quiet enough to hear it."
This philosophy is reflected in every single piece. Each glass is a dialogue between person and material.
The process: 40 minutes for a single glass
While industrially manufactured glasses are produced in seconds, Ecki invests approximately 40 minutes of pure working time in each individual casa vitri glass, whether it's a wine glass, champagne tulip glass, or sparkling wine flute. And that's just the beginning.
In each step of the process, the gas burner heats the borosilicate glass to over 1,000 °C. Through fine rotary movements and precise adjustment of gas and oxygen, the rigid material is transformed into a malleable material.
Step 1: The stem – the colored heart
Ecki starts with the stem. A colored glass rod is melted into a transparent stem and then drawn out. This creates the characteristic color that runs through the entire material – not painted on, not coated, but deeply embedded in the glass.
Step 2: The foot – the foundation
Next, Ecki shapes the foot. The charcoal plate helps him align the base, but the final form emerges solely from his intuition and experience. Without a form. Without a template.
Step 3: The Chalice – the ultimate challenge
Now comes the most difficult part. Using the blowpipe, Ecki literally breathes life into the heated material. The glass expands, and at that precise moment, he shapes the bowl with the charcoal brush and his bare hands. For a champagne tulip glass, he has to achieve the elegant, narrow shape; for a red wine glass, the generous bowl. No mold dictates the contour. There's no second chance if something goes wrong.
Step 4: Merging – three parts become one
Finally, Ecki assembles the three parts: First, the stem is joined to the calyx, then the base is fused to the stem. Every joint must be perfect, at over 1,000 degrees, in fractions of a second.

Watch Ecki at work
Words can only approximate the process. In this video, you'll see how a casa vitri glass is created, from the first flame to the finished, unique piece (in an abbreviated version, of course):
After the 40 minutes: It continues.
The time spent at the torch is only part of the story. After that, each glass undergoes further steps:
The tempering furnace: At approximately 560 °C, internal stresses in the glass are relieved. The glass then cools in a controlled manner, a process that takes hours. Only after this is mouth-blown borosilicate glass truly suitable for everyday use.
Quality control: Each individual glass is inspected by hand. Are the proportions correct? Is the glass free of stress? Is the color evenly distributed?
The packaging: Finally, each glass is lovingly wrapped in tissue paper by hand, not by a machine.
Why our glasses are "imperfect"
When you hold a Casa Vitri glass in your hand, you'll notice small differences. Perhaps a slight ripple on the rim. Perhaps one bowl is a millimeter wider than another. The stem might have a minimal tilt.
These are not errors. These are signatures.
Each of these small variations tells the story of the moment Ecki shaped the glass. Of the temperature that day. Of the movement of his hands. Of five decades of experience making decisions in fractions of a second.
In Japan, there's a concept for this: Wabi-Sabi, the beauty of imperfection, of transience, of incompleteness. Our glasses embody this philosophy without ever having consciously sought it. They are simply the honest result of genuine craftsmanship.
The difference you feel
You might be wondering: Can you really tell the difference? Is a handheld lens better than an industrially manufactured one?
The honest answer: It depends on what's important to you.
If you're looking for a perfectly identical set where every glass looks exactly the same, we're not the right choice. If you're looking for the thinnest glass on the market, you'll find it with other manufacturers; freehand work doesn't allow for wafer-thin walls.
But if you value the fact that behind your wine glass stands a human being, a master with 50 years of experience, who has invested 40 minutes of his life in exactly that one glass, then you've come to the right place.
Our glasses are for people who don't just want to drink at the dinner table, but also tell a story. People who consciously distinguish themselves from the mainstream. People who understand that true quality lies not in perfection, but in authenticity.
Craftsmanship with a future
Ecki is one of the last freehand glassblowers of his generation. The craft is dying out – not because there is no demand, but because it takes years to learn this skill. In a world of quick results, few young people choose this path.
With casa vitri, we want to give this craft a new platform. We bring traditional German glassblowing artistry into contemporary design and make it accessible to people who value something special.
Every glass you buy from us is also a statement: For craftsmanship. For time. For the people behind the things.
