Rainbow White Marble

Rainbow White Marble, sourced from the Guangxi province of China, is a natural calcite marble that is widely appreciated for its aesthetic appeal and physical properties. Below is a detailed description of its properties, composition, and recommended uses:

Physical and Mechanical Properties:

• Water Absorption: 0.10%
• Density: 2690 kg/m³
• Flexural Strength: 10.1 MPa
• Compressive Strength: 89.7 MPa
• Hardness: Typically measures around 3 on the Mohs scale (typical for calcite marble)
• Porosity: Generally low, contributing to its moderate water absorption
• Slip Resistance: As a polished marble, it may have lower slip resistance; honed or textured finishes improve slip resistance

Chemical and Mineral Compositions (% by weight):

• Calcite (CaCO₃): Predominantly the major component, often over 95%
• Magnesium Carbonate (MgCO₃): Typically less than 5%
• Trace Minerals: Include quartz, mica, and graphite contributing to color variations and patterns

Usage:

• Interior Applications: Ideal for flooring, wall cladding, countertops, and bathroom surfaces
• Exterior Usage: Possible in areas that are not exposed to extreme environmental conditions, though it may weather over time due to its calcite composition
• Decorative Pieces: Frequently used for staircases, sculptures, and fireplace surrounds

Maintenance:

• Cleaning: Use a pH-neutral cleaner to maintain its appearance and prevent etching from acidic substances
• Sealing: Regular sealing recommended to protect against stains and prolong the stone’s life
• Polishing: Maintain its luster with occasional professional polishing, and address scratches or etch marks promptly

Cutting Sizes (cm):

• Standard Slabs: Often available in thicknesses of 1.8cm or 2cm, with standard dimensions such as 240cm x 120cm
• Custom Sizes: Can be cut to customized dimensions based on project requirements

Available Common Surface Finish Options:

• Polished: Enhances the natural veining and imparts a high-gloss finish
• Honed: Provides a matte finish that is less reflective, suitable for floors with higher foot traffic
• Brushed: Offers a slightly textured surface that mimics weathered stone
• Sandblasted: Creates a rougher texture ideal for slip resistance in wet areas

Rainbow White Marble’s subtle veining and warm hues allow it to complement a wide array of design styles, making it a versatile and luxurious choice for residential and commercial projects alike. Proper installation and maintenance are essential to preserve its beauty and functionality over time.
