Black Galaxy Soapstone

Black Galaxy Soapstone is a distinctive natural stone characterized by a dark grey to almost black background, embellished with prominent white or cream veining. This combination of deep color and contrasting veining gives each slab a bold, sophisticated, and elegant appearance. Quarried in Brazil, this soapstone is well-suited for both classic and modern design aesthetics. Its natural texture and inherent subtle variations offer unique visual and tactile appeal.

Physical and Mechanical Properties:

• Water Absorption:Typically low, around 0.02% - 0.05%, indicating good resistance to moisture penetration.

• Density:Approximately 2.95 - 3.05 g/cm³, providing a solid and robust feel.

• Flexural Strength:Generally ranges from 18 - 22 MPa, demonstrating moderate resistance to bending.

• Compressive Strength:Usually between 110 - 130 MPa, suggesting good load-bearing capacity.

• Hardness (Mohs scale):Ranges from 2.5 to 3, indicating a relatively soft stone that is workable but can get scratched.

• Porosity:Low porosity, enhancing its suitability for applications in moist environments.

• Slip Resistance:Good slip resistance, especially when honed or given a textured finish.

Chemical and Mineral Compositions (% by weight):

• Talc:Main component, approximately 40% - 60%, providing its characteristic softness.

• Magnesite:Around 20% - 30%, contributing to its density and durability.

• Chlorite:Comprising 10% - 20%, influencing its distinct color and texture.

• Other Minerals:Various accessory minerals such as Serpentine and various silicates making up the remainder, affecting its specific color variations and veining patterns.

Usage:

• Countertops and Worktops:Excellent for kitchen and bathroom countertops due to heat and stain resistance.

• Fireplace Surrounds:Its heat-resistant nature makes it ideal for fireplaces.

• Flooring:Suitable for both residential and commercial flooring projects.

• Wall Cladding and Backsplashes:Offers a striking visual effect in both kitchens and bathrooms.

Maintenance:

• Requires periodic sealing to maintain its appearance and resist staining.
• Regular cleaning with mild soap and water is recommended.
• Surface oils can enhance its color over time.

Cutting Sizes (cm):

• Commonly available in slab sizes of 250 cm x 150 cm and tile formats of 30 cm x 30 cm, 60 cm x 60 cm.
• Custom sizes can often be produced to meet specific project requirements.

Available Common Surface Finish Options:

• Honed Finish:Smooth, matte surface offering a classic, understated look.

• Leathered Finish:Textured surface providing a unique tactile feel and enhanced slip resistance.

• Polished Finish:While not common due to the stone’s natural characteristics, some providers may offer polished finishes for those seeking a more reflective surface.

Black Galaxy Soapstone is versatile and can be adapted to a variety of designs, making it a popular choice for those seeking both aesthetic beauty and functional performance.
