We have seen many concept fireplaces. Here is the latest concept indoor/outdoor fireplace designed by Camillo Vanacore. The concept gas fireplace is made from a special kind of ceramic that has been discovered recently. The unique concept fireplace is cream in color when there it is off. But when you light a fire inside, the fireplace becomes transparent as the heat increases allowing you a clear view of the fire inside. After the fire dies out, the ceramic fireplace regains its original color as it starts to cool down.
