Pierre de Jaumont Limestone

Pierre de Jaumont is a unique limestone known for its distinctive bright golden yellow to honey tones, accented with occasional subtle brownish shades. This limestone is quarried in the Lorraine region of France, specifically in areas like Roncourt, Saint-Privat-la-Montagne, Malancourt-la-Montagne, and Marange-Silvange. The stone is appreciated globally for providing a warm and luminous appearance to both interior and exterior designs.

Physical and Mechanical Properties

• Color Base: Bright golden yellow, honey, sometimes with subtle brownish shades.
• Texture: Fine to medium grain; smooth surface that can be polished, honed, or left with a natural sawn finish.
• Pattern: Generally uniform with natural veining and occasional fossil traces.
• Density: Approximately 2040 kg/m³.
• Water Absorption: Typically low, ensuring good durability.
• Flexural Strength: Around 5.8 MPa, indicating moderate flexibility.
• Compressive Strength: Approximately 22 MPa, which demonstrates the stone’s ability to withstand compressive loads.
• Porosity: Medium, which can affect water absorption and weathering resistance.
• Hardness: Moderate, allowing for detailed carving and shaping.
• Slip Resistance: Variable depending on finish, with honed surfaces providing higher slip resistance than polished ones.

Chemical and Mineral Compositions (Approx. % by weight)

• Calcium Carbonate (CaCO3): Typically comprises the majority, usually over 90%.
• Magnesium Carbonate (MgCO3): Present in small amounts.
• Silica (SiO2): Minor component that may contribute to texture.
• Iron Oxides (Fe2O3): Gives the stone its characteristic golden hue.
• Alumina (Al2O3): Also found in trace amounts.

Usage

• Interior Design: Floors, counter-tops, wall cladding, and decorative elements.
• Exterior Applications: Facades, paving, and outdoor architectural features.
• Monuments and Sculptures: Historical and new sculptures due to its workability.

Maintenance

• Cleaning: Regular cleaning with pH-neutral products to maintain appearance.
• Sealing: It’s advisable to use a sealant to protect against stains and moisture.
• Repairs: Professional repair kits are available for minor damage.

Common Surface Finish Options

• Polished: For a high-gloss, reflective surface.
• Honed: Matte finish, providing a smooth but non-reflective appearance.
• Natural Sawn: Retains the stone’s natural texture and appearance.
• Bush-Hammered: For a textured, non-slip surface.
• Sandblasted: Provides a slightly rough surface, reducing slip risks.

In summary, Pierre de Jaumont Limestone is a versatile and aesthetically appealing material suitable for a range of architectural and decorative applications. Its combination of beauty, durability, and workability makes it a popular choice for both traditional and contemporary projects.
