4. Tarnish resistance
Tarnish resistance is a crucial characteristic influenced by the alloy composition of these reddish-hued golds. While gold itself is highly resistant to tarnish, the addition of copper, which is prone to oxidation, inherently reduces the alloy’s resistance. The extent of this reduction is determined by the copper percentage and the presence of other metals within the alloy. Higher copper content typically correlates with a lower resistance to tarnishing. For instance, a piece crafted with a higher copper percentage may exhibit a surface darkening over time due to copper oxidation, a process accelerated by exposure to moisture and environmental pollutants. This susceptibility to tarnish directly impacts the longevity and maintenance requirements of the jewelry.
The inclusion of certain metals, such as palladium or silver, can mitigate the tarnishing effect. Palladium, in particular, enhances tarnish resistance, even in alloys with relatively high copper content. Silver, while generally less effective than palladium, can still offer some protection against oxidation. However, if silver is the dominant secondary metal and the alloy is exposed to sulfur, silver sulfide tarnish may form. Jewelry exposed to chlorine, such as in swimming pools, may also experience accelerated tarnishing. Regular cleaning with appropriate jewelry cleaners helps to remove surface tarnish and maintain the alloy’s original color. Proper storage in airtight containers can also minimize exposure to environmental factors that promote oxidation.
In summary, tarnish resistance is a significant factor affecting the durability and aesthetic appeal of copper-gold alloys.
