3351. Lustre

3351.    Lustre is so characteristic as to have formed the common expression "metallic lustre."

3352. Weight

3352.    Weight is also a rough distinguishing characteristic.

3353. Fusibility

3353.    Fusibility is a property common to all metals. Before some metals are rendered fluid by heat, they become pasty; such is an indication of malleability. The following table gives the degrees (Fahr.) of heat at which metals fuse:
