- Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium, manganese, nickel, or zinc) and sometimes non-metals, such as phosphorus, or metalloids such as arsenic or silicon. These additions produce a range of alloys that may be harder than copper alone, or have other useful properties, such as strength, ductility, or machinability.
- Seattle Neighborhoods: Madison Valley — Thumbnail History (historylink.org)
Madison Valley is a Seattle neighborhood located just east of Capitol Hill and the Central Area, south of Madison Park and north of Madrona. A new-old community, it is best located at the small business district near Madison Street and Martin Luther King Jr. Way. According to community leaders, its boundaries are Madison on the north, Lake Washington Boulevard and Dorffel Drive on the east, 23rd Avenue E on the west, and Denny Way to the south. The community, at one time a deteriorating hollow that affluent Madison Park and Denny-Blaine residents hurriedly drove by, has changed. Today the neighborhood is festooned with small parks, two greenbelts, a pea patch, three schools, craftsman-style houses, and a cozy upgraded business district that boasts several of Seattle’s best neighborhood restaurants.
