Copper gutters turning black.

You may hear the greenish color of oxidized copper referred to as patina. The chemical reaction between copper oxygen and airborne sulfur creates a film of copper oxide and copper sulfide on the surface of the bracelet. Paint it on it clings to vertical surfaces and cleans copper. Copper gutters are our specialty and we stock 6 different profiles in a number of sizes and thicknesses.

We ship custom lengths of gutters up to 20 ft. Within days the shine will begin to fade. Along with our copper gutters we carry a complete line of copper downspouts elbows hangers. This copper gutter has been partially cleaned by painting on the copper cleaning gel and washing it off.

After a month or two they will really start to develop streaking discoloration and browning. Long and we also offer custom fabrication and are happy to build some gutters to your specifications. Copper is a popular choice for quality roofing gutters and downspouts as well as roofing fixtures and decorative elements on walls entryways and basically anywhere it adds a design element. This beautiful metal is both lightweight and malleable making it an excellent choice for custom residential and commercial projects.

The overheating can be caused by excessive current in the wires or a lightning strike and it will usually be accompanied by melted or discolored insulation near wire connections. But overheated copper wires will form a dark gray to black oxidation patina on the exposed wire surfaces similar to what happens to an overheated copper pan on a stove. After the gel melts the tarnish scrub off then neutralize. In many more years they will turn green and black.
