Copper

General Information
Copper is an easily fabricated, malleable, ductile metal with very high thermal and electrical conductivity. It can be easily shaped to desired forms and dimensions by any of the common fabricating processes such as rolling or stamping. Copper has a brownish-orange color, setting it apart from other metals. It can most commonly be spotted on the penny.
To produce copper, the ore is first mined, then put through a series of processes to refine and purify the copper. The main ore is a yellow copper-iron sulfide called chalcopyrite. Copper is mined as major deposits in Chile, Indonesia, the USA, Australia, and Canada, which together account for around 80% of the world's copper.
The maintenance needed for copper upkeep is very low. Due to copper's antimicrobial nature, it is the perfect choice for sinks and fixtures. Harmful microbes die after just a few hours of habituating on copper, erasing the need for any harsh chemical cleansers or solvents. A quick rinse with mild soap and water is all any quality copper kitchen, bath, or sink may need for cleanup.
Environmental Impact
Like other metals, copper is 100 percent recyclable and retains its quality (its chemical and physical properties) when recycled. More than 30 percent of the world’s annual copper demand is met through recycling. Additionally, copper has a long lifespan and is very durable; therefore, the lifecycle costs are minimal.
Although copper is a relatively harmless metal, too much copper can still cause health issues. People that live in houses that still have copper plumbing are exposed to higher levels of copper than most people because it is released into their drinking water through corrosion. Copper contagion can lead to a flu-like condition known as metal fever that is caused by over sensitivity; however, it tends to pass within a couple of days.
Use in Interior Setting
1. This light fixture was hand spun from pure copper and is both minimalist and sculptural. It is bound to make a statement in any room that it is featured in. (Photo 59 of 1069 in Search “copper” from Designs in Cool Copper - Dwell)
2. The copper fireplace warms up this library both figuratively and literally. It is the focal point of the room and could inspire anyone using this space. (Photo 168 of 1069 in Search “copper” from Tour a New Residential High-Rise That's Uniquely "Chicago" - Dwell)
3. The use of shiny copper in this staircase stands out against the duller oak and concrete materials adjacent to it. (Photo 191 of 1069 in Search “copper” from A Radiant Sydney Home Appears to Float Above a Sandstone Ridge - Dwell)
4. Copper's brownish-red hue seen throughout the shiny sink adds variety and interest to this bathroom. (Photo 216 of 1069 in Search “copper” from Copper’s Known to Combat Viruses—Can it Help With Public Health? - Dwell)
5. This beautiful copper bathtub could be mistaken for a copper art piece instead of a functional bathroom fixture. (Photo 256 of 1069 in Search “copper” from Japanese Soaking Tubs - Dwell)
Countertop
Some common finishes for a copper countertop are a living finish, waxed finish, or a clear coat. A living finish starts as a bare copper and will oxidize and start to change colors over time. A clear coat is the most protective coating you can use on a copper countertop to protect its patina from changing. Wax is necessary to protect the patina.
