The Bronze and Aluminium are raw materials with a thin layer of corrosion protector applied in the final stages of production to slow the process of patination. Over time this coating will wear off - the speed at which this happens will be determined by the environment and the frequency of use of the item.
For Patinated Bronze items, we apply a chemical ageing process to achieve the patinated finish, followed by a layer of corrosion protector. The Casts collection pieces are not lacquered.
