Copper
Copper is a material that appears in NetHack.
Contents
Description
Copper material consists of a family of similarly-colored, copper-alloyed metals which are susceptible to corrosion but not rust. All forms of copper can be eaten by metallivores. In-game, copper items are referred to as "copper", "bronze", or "brass".
The following items are made of copper:
- Bronze plate mail
- Both types of lamp
- Brass lantern
- Bugles
- Bells
- Rings with the randomized appearance of "bronze", "brass" or "copper"
- Wands with the randomized appearance of "brass" or "copper"
Polypiling enough copper objects may create either a stone golem or a clay golem.[1]
Strategy
Depending on which rings they represent, copper rings may be worth eating for their intrinsics.
History
Copper items were introduced in Hack 1.0 with the inclusion of copper and brass as randomized appearances for wands and rings.
Origin
Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. Copper is used as a building material and a component of various metal alloys, and copper compounds are used as bacteriostatic agents (which stop bacteria from reproducing), fungicides and wood preservatives.
Copper is one of the few metals that can occur in nature in a directly usable metallic form, which led to very early human use dating back as far as around 8000 BC. In the Roman era, copper was mined principally on Cyprus, from which the material's name is derived (from Latin aes cyprium, "metal of Cyprus", later corrupted to cuprum).
Copper was the first metal to be smelted from sulfide ores, cast into a shape in a mold, and the first to be purposely alloyed with another metal. "Bronze" usually refers to copper-tin alloys, but can refer to any alloy of copper such as aluminium bronze, while brass is an alloy of copper and zinc. Copper used in buildings, usually for roofing, oxidizes to form a green patina of compounds called verdigris. Copper is sometimes used in decorative art, both in its elemental metal form and in compounds as pigments.
