Calacatta Quartz CN Slab

Before you order

Appearance: A white ground with bold grey veins that branch and meet in a web across the slab.

Quartz is manufactured, so slabs of one design look much the same; shade can still differ slightly between production batches. Ask us about the batch you will receive.

Quartz slab: Slabs typically fabricated into kitchen worktops, islands, vanity tops and wall panels for indoor use.

Slab size and thickness are confirmed with your quotation.

Cutting and grinding quartz releases fine crystalline silica dust, which is harmful to breathe; fabrication should use wet cutting, dust extraction and proper respiratory protection.

Care

Clean quartz with a mild detergent and a soft cloth, and avoid harsh, high-pH or abrasive cleaners. Quartz contains resin, so use a trivet under very hot pans.
