Chemical and Mineral Compositions:

• Calcium Carbonate (CaCO3): Predominant mineral, typical for limestone composition
• Silica (SiO2): Present in minor amounts, contributing to the stone's hardness
• Iron Oxides (Fe2O3): Likely responsible for red and gold coloration
• Organic compounds and other trace minerals: Resulting in unique patterns and variations

Usage:

BK Genesis Limestone is versatile and used in various applications such as:

• Flooring: Its durability and slip resistance make it ideal for residential and commercial floors.
• Wall Cladding: The striking appearance makes it a favored choice for both interior and exterior walls.
• Countertops: The hardness and aesthetic appeal suit kitchen or bathroom counters.
• Paving: Suitable for outdoor paths and patios due to its weather resistance.
• Decorative elements: Used in sculptural work or decorative tiles due to its unique patterns.

Maintenance:

• Regular cleaning with pH-neutral stone cleaners is recommended to maintain its appearance and prevent dulling.
• Sealants can be applied periodically to enhance stain resistance and protect against moisture infiltration.
• Avoid acidic cleaners that can react with the limestone and cause etching.

Cutting Sizes and Common Surface Finishes:

• Cutting Sizes: Typically available in common tile sizes such as 30x30 cm, 30x60 cm, 60x60 cm, and custom sizes upon request.
• Surface Finishes:
