Our Graphite Slate Waterfall Fireplace Chamber is made from thin slivers of real slate fixed to a vermiculite backing board. These cuttable panels enable you to quickly finish a fireplace opening to a superb standard; our fire chambers are the perfect backdrop for your new stove. Please Note: Colour and Pointing will vary from the photographs as each panel is handmade and is subject to variations in texture and tolerances from panel to panel.
