Dark is the most requested and purchased color (patina). Dark is the natural progression of the copper color in the oxidation process. It is achieved with a heat process to accelerate the oxidation of the copper, or to age it. The dark patina, if lightened for any reason, will darken over time and with use. It is not an automatic process, but it does indeed start to darken in a matter of weeks, sometimes even days.
We have copper sinks installed in our offices so that we can visually see what changes may occur. Low and behold, one of the girls decided to clean the bathroom with a cleaner equal to the chemicals in toilet bowl cleaner. Much to her dismay, it immediately turned the copper sink shiny anywhere the chemical touched. Fearing she was to be fired, she fested up to her wrong choice of cleaners. She was surprised to find out that I was not mad, yet intriged as to how long and what changes would happen as the sink “repaired itself”, or darkened as we claim.
Well, it was at least a week, maybe two and it start to tarnish back to a dull shiny, then a week later, I noticed it was getting more dirty penny looking. It’ s now been a little over a month and it’s back to the dark color range that we started with. Needless to say, anyone cleaning the sink, now uses the recommended soap and water method…works like a charm.
One other observation, where the sink had been lightened was toward the front of the bowl that does not recieve a lot of water/air use. Still, it darkened without the constant contact the rest of the sink received with the washing of hands.
My final comment on colors. Dark is the natural progression of the copper in the aging (oxidation) process. There are several colors on the market these days that are quite beautiful. You will notice disclaimers that color is not guarnteed and may change with use. It will turn DARK as it does naturally. If it’s sealed with a laquer, it could change, should the sealer crack or wear. Dark is natural, natural is best and can be utilized in a rustic or contempory setting.
If you have any questions, please post them and I will be glad to offer you assistance.
Will blog about Copperhead Copper Sinks again soon…thanks for reading.
