The following are a list of the materials used in tempering. Most items in this list double up as jewelry materials. Pearls are the only jewelry material not used in tempering. Pyrine, Arentine, and Firebreath Opal are the only tempering materials not used in jewelry so they cannot be requested when players are in guilds. While Brass Ingots are used in tempering, they are classified only as a smithing material.
