Fakt 1 - Origins in Antiquity

Fired clay building materials have been used since Roman times to enhance the durability of structures. These early versions of what we now call brick-slips have endured centuries of weathering — a principle of lasting strength that Tonwerk has refined to perfection.

Fact 2 - Designed for tough conditions

During the 19th century, brick-slips were specifically engineered for industrial buildings, where they had to withstand harsh maritime climates and heavy wear and tear. This exceptional durability remains a key reason for their ongoing popularity.

Fact 3 - From functional brick to architectural statement

For a long time, bricks were valued mainly for their practicality. It wasn’t until the 20th century that architects began to appreciate their aesthetic potential, turning brick facades into design icons — especially in educational buildings where durability meets style. Today, recycled brick is also finding its way indoors, adding elegant touches to wall coverings and flooring.

Fact 4 - Northern Germany's brick gothic architecture and post-war reconstruction

The iconic brick cathedrals of northern Germany stand as remarkable examples of fired clay’s role in architectural masterpieces over the centuries. After World War II, brick experienced a resurgence as a favored building material for rebuilding many destroyed cities, valued for its resilience and longevity. Modern ceramic brick-slips carry forward this rich tradition in a slim, contemporary format, blending historic craftsmanship with modern design.

Fact 5 - Traditional craft meets modern technology 

In the past, solid bricks were laid directly in masonry. Today, Tonwerk produces ceramic brick-slips using a special process: larger blocks are formed from extruded clay and then cut into multiple brick-slip segments before firing using a wire cutter. Additionally, grooves are worked into the slabs prior to firing, allowing the blocks to be carefully broken along the fracture lines after firing.
