CUPA 14

A heavy texture, non-weathering and unfading stone with a level of quartz that provides a glistening sheen.
Our CUPA 14 is the only product approved as an alternate for Buckingham Slate on historic restorations by the National Park Service, Virginia Department of Historic Resources and Historic.

Comparable slates: Very similar in look and physical properties to domestic black manufactured in Buckingham, Virginia and Peach Bottom Slate once manufactured in Pennsylvania.
