Steinzeit Berlin – Experts when it comes to stones!


There are different kinds of surface processes that can be applied to many different stones, however, the processes can differ for each stone. Besides, not every surface process might be convenient for a specific stone. Please contact us for further information or samples.  


The surface is buffed by polishing tools to create a shiny, glossy and flat surface. The level of shine can differ on different stones.


The surface is honed to obtain a dull (‘matte’) finish. Unlike brushed surface, a honed surface is flat. The colors are more muted compared to polished/shiny finish.


The surface is brushed by special brushes. The surface becomes slightly rugged as a result of the different reactions by the areas of different hardness levels on the stone. A brushed surface looks and feels like an orange or leather. There are different brushed finishes such as satinized or patinated. Satinized finish is obtained by brushing a honed surface. Patinated finish is obtained by brushing a flamed surface.


It is the process of applying high temperature to the surface of the stone to produce a rough surface. The surface finish is rougher than a brushed surface.


This process is applied to obtain an antiqued look on the surfaces of the stones such as travertine.


It is the process of filling the holes and pits that are stemming from the natural textures of the stones. The filling material are epoxy glues or cement of similar colors or transparent variants. Upon request, surface processes such as polishing or honing can be applied to a filled stone.

Naturally Split Surface:

It is the surface that is obtained naturally by splitting the blocks of stones into slabs.


It is the process of achieving the desired thickness over the whole or a part of stone.


It is the process of blasting high pressure sand over the surface of the stone. This treatment produces a dull (matte), slightly rough and non-slip surface.

Edge Profiles:

In addition to the many types of edge profiles, different edge profile processes can be worked out upon request. Please contact our sales consultants for further information. All types of edge profiles are available as sawn, honed and polished, (brushed as well in some cases). Besides, depending on the desired stone, filling is also preferable. Bigger profiles can be produced by gluing already profiled stones together. Edge profiles are applied not only to the straight edges but also to angled and round edges, though with certain technical limitations (i.e., depending on the inner radiuses and tool sizes, etc. Please contact our sales consultants for further information.)

  • Cornice
  • Half Round
  • Quarter Round
  • Bullnose
  • Beveled
  • Standard profile
  • Bushhammered
  • Sawn
  • Sandwich (Metal inserts)
  • And many more…


Stones are cut in order to mount units such as sinks, taps or stoves. These cuts can be enriched by any edge profiles. The inner edge profiles can be cut both straight and angled. It is also possible to cut out asymmetrical shapes as well as common geometrical shapes. Besides, the cutout can be designed to fit offset stoves or other units in a way that they are at the same height with the worktop surface. For this process, the inner corner is required to have minimum 3 mm radius.

  • Cutout without profile
  • Waterjet (asymmetric & 3D cut)
  • Flush mount

Draining Surface:

It is the process to create an area on the kitchen worktop lower than main surface. A minimum radius of 63 mm is required.

Drainer Grooves:

It is the process of etching slanted drainer grooves. The width for this process is 12 and maximum depth is 8 mm.

Window-sill Drainer Grooves:

It is the process of etching drainer grooves underneath the outer side of the window-sill to prevent the water from leaking towards the wall.

Drilling Holes:

Drilling holes with desired depths on the stones. This process is utilized to mount screw sockets and other parts. A minimum 3 mm of radius is required.

Beveled Cut:

The stones can be cut in varying angles as well as vertically.


It is a reinforcement method in which fiberglass fortifiers are placed in grooves underneath weak stones or stones with large cutouts. After this process, the product gains much strength.


It is the process of gluing stones together or units such as sinks to stones. It is preferable to use glues of similar color to stone color or transparent glues.

Anti-slip strips:

It is the process of placing plastic anti-slip strips in the grooves etched on the stones. Sandblasting can also be applied to produce anti-slip areas on the surface.


It is the process of engraving figures and scripts of varying depth and width. The engraved areas can be filled with colors or left as they are.
