However, when wire was first invented over 2,000 years BC, it was made from gold nuggets pounded into flat sheets, which were then cut into strips.
Silver-filled wire is made in the same manner. The bond between the two materials is permanent. Wire is measured by diameter, which is indicated by gauge numbers. The lower the gauge, the thicker the wire. A 12- or 14-gauge wire is fairly heavy, but ideal for making bangles and chokers. 10-gauge wire is very thick and stiff, while 26-gauge wire ...
