Guyuria [SEP] material used
Guyuria
Guyuria are traditional Chamorro cookies. They are also known as Chamorro jawbreaker cookies due to their historically rock-hard texture. Guyuria was originally made with flour, coconut milk, and a sugar glaze. The dough is first made as one solid mass. Small pieces of dough are pinched off. Each piece is rolled out on a wooden guyuria board or on the back of a fork. Once enough cookies are formed, a batch is fried, cooled, and finally coated with a sugar glaze. The glaze is
to cathodically protect metals that are exposed to sea water. A zinc disc attached to a ship's iron rudder will slowly corrode while the rudder stays intact. Similarly, a zinc plug attached to a propeller or the metal protective guard for the keel of the ship provides temporary protection.
With a standard electrode potential (SEP) of −0.76 volts, zinc is used as an anode material for batteries. (More reactive lithium (SEP −3.04 V) is used for anodes in lithium batteries ). Powdered zinc is used in
