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).
Beadalon is the only company in the industry that actually makes its own wire, strand, and cable for jewelry making and crafts. Other brands simply label or respool wire purchased from third party factories. Beadalon bead stringing wire is composed of tiny wires twisted together and nylon coated. The number of tiny wires, also known as strands, determines the flexibility of the wire. The larger the number of strands, the more flexible the wire will be. Therefore, 49 strand is more flexible than 19 strand, and 19 strand is more flexible than 7 strand. When choosing which type of wire to use, consider the amount of drape you want your design to have. 49 strand wire is very supple and will drape elegantly, giving your designs a thread-like appearance.
