Maintenance

• Sealing: Recommend using a penetrating sealer to prevent staining, especially for kitchen and bath installations.
• Cleaning: Use only pH-neutral stone cleaners. Avoid acids, vinegar, or bleach, which can etch the calcite.
• Polishing: Occasional professional repolishing can restore surface shine for high-traffic or public spaces.
• Regular Care: Dry mop or clean with soft damp cloth to avoid grit abrasion.

Notable Attributes

Used since Classical Antiquity in monuments such as the Parthenon in Athens. Excellent for luxury interiors, museum-grade restoration, and sculptural works. Maintains structural integrity with minimal water absorption and good strength, suitable for dry or moderately humid climates.
