Historically, explanation has been associated with causation: to explain an event or phenomenon is to identify its cause. But with the growth and development of philosophy of science in the 20th century, the concept of explanation began to receive more rigorous and specific analysis.
For making jump rings, use 10- to 18-gauge wire (2.5 to 1.3 mm). Bracelet and necklace wire components are generally made out of wire that is 16-, 18- or 20-gauge (1.3 to 0.8 mm). Earring wires are usually made out of 18- or 20-gauge wire (1.0 to 0.8 mm).
Wire diameters start at 15 Âµm and can be up to several hundred micrometres for high-powered applications. The wire bonding industry is transitioning from gold to copper. This change has been instigated by the rising cost of gold and the comparatively stable, and much lower, cost of copper.
