De Ferranti now offers rare bituminous limestone with a deep rich chocolate brown colour, tonal variation, and visible fossil remains.
This extraordinary material is quarried from an area where hard white limestone has, over the course of thousands of years, become impregnated with bitumen from underground oil beds. The specific quarry was closed in the 1930s and has only just re-opened.
De Ferranti’s Bitter Chocolate Limestone suits both traditional and contemporary interiors. It is typically supplied in tile formats: 400 by 400 by 20mm; honed and pre-sealed. Although rare in large sizes, De Ferranti can source slab and block to carve basins and form architectural details, such as staircases, friezes and cornicing. Bespoke sizes and finishes are available to order.
For indoor use only, this rare limestone can be used for floors and wall cladding. Once laid, it is given a final coat of oil and then sealed, resulting in a rich, leather-like, patina..
