Questions about Portoro Silver
Where is Portoro Silver from?
We are still confirming the origin of the Portoro Silver we hold, so we do not state it here. Ask us and we will tell you what the supplier documents show before you buy.
Is Portoro Silver good for kitchen countertops?
No. Portoro Silver is not suited to a kitchen counter. For a counter, choose granite and keep Portoro Silver for feature walls and flooring borders and inlays.
Which finish is best for Portoro Silver?
Portoro Silver can take these finishes: polished and honed. It is most often sold polished. Polished shows colour and pattern most strongly; honed and textured finishes are matt and give more grip. Ask which finish is available in the lot you choose.
How do I clean and maintain Portoro Silver?
Maintenance is high. Dark polish shows scratches and etching. Seal and use door mats. Avoid acidic and bleach-based cleaners on natural stone.
