Aluminum and the lower band, or (b) in the upper area of the lower area of the iron and copper? (c) If the pail is molten metal in place of ice and two bands are made of brass and copper, brass or copper should fall on the bucket? If you could show me how to please and so I did not understand that for the future. Thanks
