A burner for household or recreational use, such as for generating a decorative play of flames, emission of heat or use in, for instance, a hot plate or fireplace, in a generally safe, clean and efficient manner. The burner is equipped with a fuel stock holder (2, 22) provided with a fuel receiving body (5, 25, 45) from a form-retaining, isotropic, heat-resistant and porous material for retaining liquid fuel by means of absorption. The fuel receiving body (5, 25, 45) is located in a casing (9, 29, 49) with at least one flame opening (10, 30, 50) for combusting fuel at the surface of the fuel receiving body and which is connected to the fuel receiving body (5, 25, 45) without substantial residual spaces remaining between the casing (9, 29, 49) and the fuel receiving body (5, 24, 45), or the fuel receiving body is arranged freely without casing.
