In architecture, stones serve various purposes depending on the type of space in which they are utilized. The utilization of different stones requires specific surface finishes tailored to the intended space. Finishing constitutes a crucial phase in the stone production process, shaping the stone’s surface to suit its designated purpose.
The objective of finishing extends beyond aesthetic appeal and special effects; it encompasses the physical transformation of the stone’s surface to adapt it for diverse conditions and applications. Different finishing techniques are employed based on the stone’s intended use. In this context, we will explore various stone processing methods employed by the Soroush Stone Collection on black granite:
Polished Finish
Polishing is one of the most prevalent surface finishes for black granite. Achieved through a gradual abrasion process using specialized abrasives, it results in a fully polished and lustrous surface. This finish boasts the highest level of smoothness, shine, mirror appearance, and light reflection. Ideal for countertops and exterior building surfaces, the polished surface enriches colors, providing a darker aesthetic. Common applications include stairs, floors, and building facades, with caution advised in areas prone to moisture, as the surface can become slippery.
Color Polished Finish
For those desiring darker surfaces in Souran polished black granite, a special black color, achieved through thermal stabilization in multiple furnace stages, deepens the stone’s color, enhancing its contrast. This finish is well-suited for facades, internal stairs, floors, and store-side surfaces, creating an original composition when combined with bright materials or colors.
Flame Finish
Flame finishing involves subjecting a portion of the stone surface to concentrated heat, causing controlled destruction and creating a roughened surface known as flamed polishing. Beyond its aesthetic appeal, the uneven surface resulting from this process serves various practical purposes. Souran granite, in particular, exhibits high flammability compared to other stones. The Soroush stone factory utilizes a Flame device for more uniform flame polishing compared to manual methods.
Leather Flamed
Approaching the natural textures of stone surfaces, whether driven by aesthetic motives or practical considerations, has perennially captivated designers. Natural stone surfaces exhibit inherent roughness and coarseness resulting from natural weathering. One method to achieve a rough surface finish is through flaming, an operation meticulously executed at the Soroush Stone Complex using an automated device and a decentralized flame, ensuring uniformity and integration. To temper some of the roughness induced by the flame process, leathering the stone surface is recommended. This not only mitigates the created roughness but also imparts a slightly darker gray hue to the stone.
These surfaces, characterized by proper friction, present an excellent option for various applications such as flooring, outdoor stairs, areas adjacent to swimming pools, sidewalks, washroom and bathroom floors, parking lot floors, and, notably, building facades owing to their attractive texture and color.
Honed
Honed represents another stone processing method where the stone surface undergoes polishing but with a distinct technique, resulting in a matte finish that exudes a unique beauty. Honed polishing imparts smoothness and softness to the stone surface, devoid of visible scratches, making it predominantly suitable for decorative purposes.
Bush Hammer
Among the most luminous surface finishes for Souran black granite is the Bush Hammer finish, characterized by a light gray color. This finish is achieved through rotary contact and specialized, highly durable sharp tools inside the SAAB machine, imparting a needle-like structure (surface pores) to the stone surface. With heightened friction compared to other finishes, it proves an excellent option for floors in wet and slippery environments. Recommended applications include exterior stairs, bathrooms, and areas surrounding swimming pools. The bright color of this finish, when combined with other dark Souran stone finishes, enables designers to craft myriad creative designs.
Cut
Cut polishing involves cutting the stone plate at various angles using tools to create parallel and shallow cuts. This finishing finds its place in decorative spaces.
Broken Cut
A particularly exquisite stone processing method is the broken-cut finish. Similar to a cut finish, this method involves breaking the cut ridges during the subsequent process, imparting a distinct and beautiful appearance to the stone.
Cut Hammer
To achieve this finish, grooves are first created on the stone surface with varying depths and distances according to the customer’s specifications and the designer’s intended use. Cut finishing serves as a machine finish, serving as the foundation for other finishings. By incorporating grooves with different and attractive shapes, we elevate the finish to a distinct level of the cut hammer.
Advantages of the cut hammer include its vivid gray color, the allure of the grooves complemented by the roughness and intensity of the cut hammer (or Bush hammer), and the unique possibility to create this finish considering the hardness of granite, a feat deemed challenging in other stones. Applications include building facades, especially villas, and interior design, particularly in the context of fountains.
Scratch Finish
An alternative to polished surfaces involves the creation of fine, shallow, parallel grooves that are uniform across the surface. When applied to Souran black granite, this technique imparts a gray color and a relatively rough texture. If installed seamlessly, the bond between the stones remains hidden, presenting a cohesive, unified appearance. The versatility of the gray color, combined with other hues, grants designers the freedom to explore a diverse array of creative designs.
Sandblasted Finish
Sandblasting is a finishing technique that results in a striking stone surface. This process, performed using a sandblasting machine, alters the stone’s surface, providing a texture reminiscent of flame polishing. Typically applied to large-size plates and slabs, this finish adds a distinctive aesthetic appeal.
Colored Leather & Flamed Finish
For designers seeking darker colors and a more contrasting space, the colored leather flame finish offers a solution. This process involves applying special epoxy paint in three steps to the flamed stone, followed by thermal stabilization in the oven after each step. The resulting colored leather flame (epoxy) finish penetrates the stone texture, ensuring longevity and resistance to external factors. Widely embraced for interior environments and stairs, its compatibility with various color materials enhances design possibilities.
Colored Sandblasted Finish
Introducing color to the sandblasted surface through a three-component paint and stabilizing the color temperature in the oven yields a colored sandblast finish. Successfully utilized around elevators, columns, building facades, and other architectural elements alongside lighter stones, this finish provides designers with greater flexibility in implementing diverse themes.
Cut Flamed Finish
A distinctive stone processing method of cut flaming involves creating parallel patterns through parallel grooves on the surface of flamed stone while preserving its natural essence. The depth, width, and spacing of these grooves can be customized based on customer preferences. This finish, notable for its frictional properties, is particularly suitable for sloping surfaces such as parking lot floors and is commonly employed in building facades.
Linen Finish
Among the most frictional finishes on granite stones is the linen design, characterized by perpendicular grooves at regular intervals. This aesthetically pleasing surface is versatile, finding application in sloping car surfaces, interior and exterior views, stairs, and other architectural elements, depending on the designer’s vision and customer preferences.
Colored Honed Finish
Recommended for situations requiring a smooth, entirely dark, and matte surface, the colored honed finish combines honed polish, resulting in a smooth matte surface, with the application of special epoxy paint for a completely dark appearance. This finish’s striking beauty empowers designers to explore various uses and incorporate a wide range of combined designs.
Cut & Polished Finish
An effective way to elevate the visual impact of granite stone is through the application of parallel grooves on polished surfaces, known as a polished cut finish. This method allows for customization of groove intervals, depth, and width based on customer preferences, offering flexibility in design. Grooves can be created linearly along the length of stone tiles or diagonally. The juxtaposition of polished intervals with cut grooves creates a captivating color contrast, making it a popular choice for building facades.
Irregular Cut Finish
While consistent grooves along the length of stone tiles enhance their appeal, a continuous pattern may lead to visual fatigue. Introducing irregular grooves on the stone’s surface offers a unique finish that has garnered attention from designers and architects alike, providing a distinctive aesthetic.
Cut Bush Hammer Finish
Creating a color contrast on stone surfaces can be achieved through the bush hammered & cut finish. Utilizing the brightness of the gray spectrum in Souran stone, parallel grooves are applied along the length of the stone at regular intervals (e.g., approximately 10 cm), enhancing the color contrast. The Bush hammer finish, known for its low slipperiness and high friction, proves to be an excellent choice for areas requiring increased traction. This finish is particularly well-suited for locations with higher safety considerations.
