Cone is an innovative charcoal grill that allows for efficient heat regulation: when high heat is required, users simply lift the coal grid and thus the heat source. To reduce the heat, the coal grid is lowered and thereby the air supply decreased. At the lowest and coldest position, the air ducts are closed. Since the coal grid can be lifted up to the edge of the cone after the barbecue, the grill can be transformed into a fireplace that only needs few logs of wood to create a great ambience.
