Century Dictionary and Cyclopedia

1. n. A fusible alloy used for joining or binding together metal surfaces or joints, as the edges of tin cans, jewelry, and kitchen utensils. Being melted on each surface, the solder, partly hy chemical attraction and partly by cohesive force, binds them together. After cleaning the edges to be joined, the workman applies a solution of zinc in hydrochloric acid and also powdered rosin to the cleaned surfaces; then he touches the heated soldering-iron to the rosin, and holding the solder-bar and iron over the parts to be joined melts off little drops of solder at intervals along the margins, and runs all together with the hot iron. There are many of these alloys, as soft solder used for tinware, hard solder for brass and iron, gold solder, silver solder, spelter solder, plumbers' solder, etc. Every kind is used at its own melting-point, which must always be lower than that of the metals to be united, soft solders being the most fusible.
2. n. Hence Figuratively, that which unites in any way.
3. n. Gross fiattery or fulsome praise, particularly when used for selfish aims.
4. To unite by a metallic cement; join by a metallic substance in a state of fusion, which hardens in cooling, and renders the joint solid.
5. Figuratively, to close up or unite firmly by any means.
