4. Top 5 FAQs
Q1: What makes Portoro Gold Marble different from other black marbles?
A: Unlike other black marbles (like Marquina, which has faint white veins), Portoro Gold features distinctive luminous golden and white veins on a deep black base. This unique color combination offers a regal, dramatic, and ultra-luxurious feel, resembling liquid gold streaked across a midnight sky.
Q2: Is this marble suitable for kitchen countertops?
A: Yes, absolutely. As a natural marble, it requires professional sealing (we recommend high-quality impregnating sealers) to protect against stains. For heavy-use kitchens, a Polished finish maximizes beauty, while a Honed/Leathered finish offers better scratch resistance.
Q3: Does every slab look the same?
A: No, like all natural stones, each slab is uniquely beautiful. The density and flow of the golden veins vary. We carefully select and group slabs from the same quarry block to ensure excellent consistency for large projects.
Q4: What finish is best for flooring?
A: For floors, especially in high-traffic or wet areas (bathrooms), Honed or Leathered finishes are highly recommended. They are less slippery than polished and better hide daily wear and tear.
Q5: How to maintain Portoro Gold Marble?
A:
- Clean regularly with pH-neutral stone cleaners (avoid vinegar, lemon, or abrasive cleaners).
- Wipe up spills immediately, especially acidic substances like coffee, wine, or citrus.
- Re-seal the surface every 1-2 years to maintain optimal protection.
- Use trivets under hot pans and coasters under glasses to prevent etching and scratches.
