Flammleisten and Wellenleisten: Understanding Ripple Patterns
Flammleisten and Wellenleisten: Understanding Ripple Patterns
By Tom Matthews · Ripple Molding LLC
If you've ever looked closely at a 17th-century Dutch painting, there's a good chance the frame surrounding it caught your eye almost as much as the artwork itself. Those mesmerizing, rhythmic ridges carved into dark wood are called ripple molding — and they come with a vocabulary all their own. Two German words sit at the heart of that vocabulary: Flammleisten and Wellenleisten.
Understanding the difference between these two terms is the key to understanding every ripple pattern you'll encounter on a Dutch Golden Age frame. Let's break them down.
Where the Names Come From
Both terms are German, which makes sense: the machines that produced ripple molding almost certainly originated in Nuremberg, Germany, during the late Renaissance. The craft then migrated to the workshops of the Netherlands, where it became synonymous with the austere, black picture frames we now associate with Rembrandt, Vermeer, and their contemporaries.
The inventor of rippled moldings is generally credited to Johann Schwanhardt, who was born in Rothenburg and lived in Nuremberg in the early 17th century. His innovation — the waving engine — was one of the world's first three-axis machines, built at a time when most machinery in Europe was still made largely of wood.
Wellenleisten: The Wave That Rolls Toward You
Wellenleisten translates roughly to "wave strips" or "wave molding." In this pattern, the ripples undulate up and down — imagine ocean waves rolling toward you if you were standing at the edge of the frame. The ridges run perpendicular to the length of the molding, creating that classic, evenly spaced ripple most people picture when they hear the words "Dutch ripple frame."
On the waving engine, wellenleisten is produced by adding an eccentric wheel to the bed of the machine. As the length of wood passes under the scraping blade, the wheel makes it rise and fall in a steady, consistent rhythm. The result is a pattern of uniform crests and troughs along the full length of the molding.
Flammleisten: The Flame That Dances Side to Side
Flammleisten means "flame strips" or "flame molding." Instead of undulating up and down, the ripples in flammleisten move from side to side — a lateral shimmer that looks like a flickering flame running down the length of the wood. It's a subtler, more restless movement than wellenleisten, and it gives a frame an entirely different visual energy.
The technique for producing flammleisten is different, too. Rather than an eccentric wheel, the waving engine uses a jig with a horizontal wave cut into its side. As the wood feeds through the cutting block, this jig forces it to shift right and left, producing that signature lateral ripple.
The quick distinction: Wellenleisten ripples move up and down (like ocean waves). Flammleisten ripples move side to side (like a flickering flame). Everything else in the world of ripple molding is built on top of these two fundamental motions.
Beyond the Basics: Compound Patterns
Once you have wellenleisten and flammleisten as your two building blocks, things get interesting. By combining these motions, adjusting their frequency, or alternating them in sequence, frame makers throughout the centuries developed a whole family of compound patterns. Here are a few of the most recognized:
|
Pattern |
Description |
|
Steady Ripple |
A pure wellenleisten pattern — even, uniform waves running the full length. The most common and recognizable Dutch ripple. |
|
Flame Ripple |
A pure flammleisten pattern — lateral, flickering movement from side to side along the molding. |
|
Skip Ripple |
Alternating sections of rippled and smooth wood, creating a broken, rhythmic pattern. |
|
Herringbone |
Angled ripple sections that meet at the center of the molding, creating a V-shaped chevron effect. |
|
Basketweave |
Sections of wellenleisten and flammleisten woven together in alternating blocks, mimicking the look of a woven basket. |
Each of these patterns required its own specialized jig and careful setup on the waving engine. A skilled operator could produce an enormous range of decorative effects — all from a single machine and a set of interchangeable followers and scrapers.
Why It Matters for Picture Frames
Understanding flammleisten and wellenleisten isn't just academic — it's practical. When you're choosing a frame for a painting, a print, or a mirror, the ripple pattern changes the entire feel of the piece. A steady wellenleisten ripple is calm and structured, well-suited to formal portraits and still lifes. A flammleisten pattern is livelier and more dynamic, a natural complement to landscapes and expressive work. A basketweave or herringbone brings a richness and complexity that can stand up to large-format or heavily detailed pieces.
These are the same choices frame makers were weighing in Amsterdam and Haarlem four hundred years ago. The vocabulary is German, the tradition is Dutch, and the craft is alive and well today.
A Living Tradition
Though ripple molding is often called "Dutch ripple," the style was never confined to one country. It appeared across the Netherlands, Germany, Spain, and beyond. What tied it all together was the waving engine and the two fundamental motions it could produce: the vertical wave of wellenleisten and the lateral dance of flammleisten.
Today, I make every one of my moldings using the same principles Johann Schwanhardt pioneered in the 1600s — scraping steel profiles guided by pattern followers, producing ripple patterns one pass at a time. The technology has evolved but the geometry and the craft are the same. Every ripple you see in my frames traces a direct line back to those early Nuremberg workshops.
