These are beautiful feature firestones moulded from a non combustible formula as a decoration amongst the flames of living flame gas fires. They were made as samples for an architect in London and I’m trying to remember his name but it was over thirty years ago now. It was the advent of the hole I. The wall fireplace concept and open plan living and minimalism and he was pioneering these objects at the times for his high end clients. These has been in storage for ever and forgot I had them. We used them amongst flames within a room set exhibition for three days and then in a false fire in the wall fireplace in our interior design showroom purely as ornaments. Collection from Tockwith York preferred or can post if necessary. Any questions send to 07525 852697, thank you.
