![]() TemperatureĬhemical reactions happen when molecules move and collide with each other. ![]() This knowledge will surely impress your friends and relatives as they marvel at the elegance of your copper and the sophistication it brings to both your home and your conversations. Knowing these factors will not only help you appreciate the patina on your copper but will also allow you to influence how the patina forms. Several factors in the copper and the surrounding environment can affect how fast patina forms, and what colors it will have. The faster a chemical reaction is, the more products will form. Why does copper patina over time? As we have established, patina forms on copper because of chemical reactions. Shellfish, such as crabs, have greenish-blue blood because the metal atom that carries oxygen in their bodies is copper. ![]() It is interesting to note that human blood is red because the molecule that carries oxygen in our blood is iron, which produces a red color. When mixed in small amounts and held on the surface of copper, these three compounds produce the pleasant luster of patina. Each of these three compounds can form beautiful crystalline structures on their own, like precious rocks. Darker greens indicate an abundance of malachite and brochantite, while blues suggest that azurite is abundant. The products that result from Equations 4-6 in the previous section each has their own shades of color:ĭepending on what combination of these three is present, the color of the patina can vary from shades of green to shades of blue. This section describes in broad terms why the presence of certain chemical compounds can affect the green and blue hues often seen in patina. The next section explains the physics and chemistry of why the colors of patina can vary so much from place to place and from time to time. Patina has different colors and patterns that depend on the unique experience that each copper object has had. Equation 4: 2CuO + CO2 + H2O → Cu2CO3(OH)2.The chemical reactions described above can be written in atomic symbols as follows: The result is a compound called brochantite, which varies in color from shades of dark green to emerald. The third reaction that influences the color of patina is when four molecules of copper oxide from Equation 2 reacts with one sulfate molecule and three water molecules (Equation 6). The result is azurite, which is a compound that varies in color from shades of blue to shades of purple. The second reaction that adds to patina’s color is when three molecules of copper oxide from Equation 2 can react with two molecules of carbon dioxide and one molecule of water (Equation 5). The result is a compound called malachite (Equation 4), which varies in color from shades of dark green to shades of blue. The first reaction that gives patina its color is when one molecule of carbon dioxide and one molecule of water, both in the air, react with two molecules of copper oxide on the surface of the copper. It contains carbon dioxide, which we breathe out, along with water vapor. The greenish and blueish colors of copper’s patina come from the next set of reactions.Īir contains more than just the oxygen that we breathe. If sulfur is present on the surface of the copper, then the two can react to form copper sulfide, which is black (Equation 3). This copper oxide from reaction 2 is the main culprit that will later form the colors of the patina. The copper dioxide then reacts with more oxygen to form copper oxide (Equation 2). Both happen when oxygen in the air interacts with the metal atoms in the presence of water.Ĭopper reacts with oxygen that is in the air, resulting in copper dioxide (Equation 1). The Chemical ReactionĮver ask yourself, “Why does copper turn green?” The formation of patina on copper is similar to the formation of rust on iron. This knowledge will also allow you to influence what color of patina forms, and how fast it will do so. Knowing how copper patina forms will give you a deeper appreciation for the unique patina that appears in your family's history. The shades of patina that form on the surface of a copper furnishing can store the memories of meals, spills, new homes and life changes over the course of centuries.Ĭopper is more than a shiny metal - it is one that can be adorned with beautiful carvings that tell a story. The natural changes that happen to copper objects make them a one-of-a-kind symbol of heritage that's hard to replicate. The beauty of copper is unique among decorative materials because the changes it undergoes are unique to each home and location. Copper home furnishings provide an elegant beauty because copper is a “living” metal, meaning it changes color over time.

I don't see a lot of white people really speaking up in defence of Black and Indigenous people. It is a clear reminder to us all that we have to change our thinking, we have to change our practice, we have to change and reimagine a better society for everyone. Watching the murder of George Floyd under the boots, literally, of a white policeman in America last year was one of the most sickening, devastating things I've ever seen. It was incredibly brave what she did, it was really an act of great political courage and remains so. A great reminder of what we must all shelter Black and Indigenous peoples from. Not just of the American Songbook, but of the Global Songbook. ![]() So, to me, this is one of the most important songs. It's astounding to me that we're still dealing with systemic racism, we're still dealing with that cruelty and that intolerance and that horror. We remember what other human beings who happened to be a different colour from someone else were put through. I feel, to this day, it's still an incredibly important song. The atrocity that she was covering with this amazingly beautiful song about something abominable. I could feel that it was about something really painful, I just didn't know what was about.Īs I got older, I started to learn what she was singing about. Through her I discovered the great Nina Simone, Peggy Lee, Ella Fitzgerald, Julie London, a whole gamut of jazz singers that remain touchstones throughout my career.īut when I heard Billie Holiday sing 'Strange Fruit', I didn't understand what the song was about. Sung by an absolute master.īillie Holiday is one of my all-time favourite artists. The darkest, saddest song I've ever heard of my life. I think this is one of the most important songs ever written. I don't think I'll ever divorce myself fully from that person, because it feels like that's my real identity and everything else is just kind of a costume. Who yearned to be part of the scene and just never was. Yet I still feel like that kid at school who was pretending there was somebody calling me up. This is what I've done with my whole life, sing in bands.' Then I have to sort of sit and think, 'Wow, I really am. And he's like, 'No, actually, you really kind of are.' My husband's always saying like, 'What is your problem? You're a rock star!' and I'll go 'I'm not a rock star'. To this day, I can just listen to it on loop over and over and over again. I just really related to what she was saying and how she was saying it. Those who don't sail through life, who aren't given the backstage pass. She was basically singing about outsiders and freaks. To not have the most perfect figure, or the perfect face, or personality'. When I heard Janis Ian sing the song, I was like, 'this person understands me, and understands what it's like not to be the most popular girl in class. I felt like a frustrated, confused, unattractive, disempowered, unpopular child. When I heard the song for the first time, I just felt it had been written for me. ![]() ![]() Twitter, Facebook, Google+ and other Social Media Services Google Reader could have become a sort of Flipboard for the web, but Google let Reader stagnate. The structure encourages readers not to follow too many sources or worry about reading every little thing they publish.įlipboard has been a smashing success, and it’s a good example of the kind of reading app that average people would prefer. Each source is presented separately, where users can flip through stories with images like they would flip through a magazine. Flipboard doesn’t display an unread count that turns the reading app into another inbox you have to keep on top of. Flipboard allows you to add sources they want to read content from - you can even add RSS feeds directly, but it doesn’t feel like using an RSS reader. Google Reader doesn’t provide a way to filter these feeds for the information most relevant to you, or even just eliminate duplicates - it aims a fire hose of information at its users and tells them to drink.įlipboard, Currents, Pulse and Other Reading AppsĪpps like the popular Flipboard, but also Google Currents and Pulse, discard much of the old RSS experience.
