Brass can be cast, forged, spun or stamped. Cast and forged brass are expensive. With these two forms - heat is applied to brass to mold it into shape. These utensils are cast - this means, molten brass is poured into a cast or and then scuffed to give them their beautiful shape. Plated brass is the cheapest form of brass, since plated brass is thinned by a machine into sheets and pressed into shapes. Usually the thicker the walls of brass, the more expensive it tends to be, as thicker articles tend to be handmade.
