Where do you find the second shield in Legend of Zelda oracle of seasons?

once you get the magnetic glove, go into subrosia and you will find two ores hidden in two chests in different areas of subrosia, they both require you have the magnet glove and once you get both of them, go to the subrosian melters on the far left side of the map, they will turn it into a hard ore, (you have to have a shield for this) go to the subrosian smithy and when they ask to make you shield fine, you will say do whatever and they will give you the next shield
