copper oxidation


Jean-Michel Basquiat in his Great Jones Street studio, in front of a piss painting of himself by Andy Warhol. The canvas had been covered in the copper paint and urine was applied. The urine reacts with the copper paint to create oxidation, then Basquiat’s image was silk-screened onto the canvas.

Okay, guys, I keep seeing people who keep thinking that only a few or some of the characters in RWBY follow the color naming rule, and people don’t fully know the details of what the rule actually is, so… here’s the image Monty released way, way back before volume 2. He tweeted it, and I saved it before Twitter made it impossible to view the full size image.

Knowing the naming rules can be helpful in creating an OC, which is exactly why Monty released the color naming rule. So, regardless of whether or not you’re interested in the rest of the info in this post, I hope you find the above image useful! :D Also…

“Thus all the names in RWBY (Minus Ozpin… for reasons….) follow this rule.” Every single character except Ozpin “for reasons.”

No more of this “Ironwood doesn’t follow the color naming rule” “Glynda doesn’t follow the color naming rule” “So-and-so doesn’t” stuff. All of them do. And paying close attention to the rules will help you understand how they do follow the rules.

  • Be a color
  • Mean a color
  • Sound like a color
  • Make people think of a color

The name can live up to one or more of those requirements, and it can be

  • First name
  • Last name (Example: Lisa Lavender, the female reporter from volume 1 episode 1. Lavender is a purple flower.)
  • First and last name (Example: Weiss Schnee. Weiss means white, and Schnee means snow, which reminds people of white. Or Dove Bronzewing. Doves are white/gray birds, and Bronzewing has the word bronze in it.)
  • A combination of the first and last names (Example: Cyril Ian, the male reporter from volume 1 episode 1. Miles said his full name is Cyril Ian because it sounds like cerulean.)

Below the Read More is a list of all the named characters as of volume 2’s finale and how they follow the color naming rule, as well as my take (shared with many other people, I’m sure) on how Ozpin doesn’t follow the rule.

Black shiny Delafossite rosettes.

Delafossite is a copper iron oxide mineral.  Delafossite is usually a secondary mineral that crystallizes near oxidized copper and is rarely a primary mineral. The mineral was given the name delafossite in honor of the French mineralogist and crystallographer Gabriel Delafosse (1796–1878)


Sometimes I take time-lapsey photos of drawings as I work on them.
Side note: coloring in Rabbit’s hair completely took the life out of my brush pen but it was worth it

[Image description #1: It’s a pencil sketch of The Spine, a robot with black lines outlining his cheekbones, jaw, and eyebrows. He also has vertical lines on his mouth and horizontal lines on his neck. He wears a fedora and a striped button-down shirt. Beside him is Rabbit, a robot with defined face plates, long and slightly unruly hair, a metal rivet hair clip, and vents in the side of her face. Her head is held up by wires in place of a neck. Her angular collar can be seen. Both robots are smiling.
#2: The picture is now inked with black pen, and every line is straight except for the lines on the robots’ clothes.
#3: The picture is colored in with colored pencil. The Spine is silver, with green eyes. His shirt and fedora are both black and gray, and part of his collar is red. Rabbit has black hair, partially oxidized copper face plates, a red collar, and heterochromatic eyes (one green, one blue).]


Auction #1

This necklace was previously listed on my website for $165. Unfortunately, sometime when I was transporting it from my home to a fair, the last little quartz point on the right side broke off. It was silly of me not to protect the piece better, I just put it in a big box with all the other jewelry and let it jostle around. :( This piece is made with a very large high quality rainbow moonstone with double flash, three pieces of all natural Zambian citrine, and three pieces of clear quartz. It is set in oxidized copper. The pendant measures 3.3″ tall and the chain measures 20″

Starting Bid: $1 (shipping is free if you’re in the US, if you live outside the US message me for shipping quote)

Auction End time: 6:00 pm, Pacific time

Place your bids by replying to or reblogging this post. All the auctions will end starting 6:00 pm, Pacific time. I’ll message the winners right away and they must provide me with their emails.

It’s not fair to me or the other bidders! Thank you.

Re: your last big post about elfs, I'm a little perplex. It seems that Mirrodin Elfs are just "bad elfs with Green Skin", is that really enough? You were complaining about Kor, too. And after a quick search, I can't even see what you find good in Otaria Elfs. The only ones I actually find good are Lorwyn.

EVERYTHING on Mirrodin is awesome. It’s important to note that Mirrodin elves aren’t “green with nature” but actually “Oxidized copper” and most of them use copper in the rest of their design. Also, they don’t have hair. What looks like hair is actually metallic cord.  Take a look at this.

Yes, her face is the same as a human, but that’s not hair, and as we can tell more clearly from other Viridian elves, those aren’t gloves and boots either. Those are part of her.  Now, it’s a bit downplayed because everyone on Mirrodin is super awesome, with the Vulshok humans being basically the coolest thing ever, but the fact remains that there’s a lot going on for the Viridian other than being green.

As for Otaria elves, there’s pre-Mirari and Post-Mirari. Pre-Mirari elves, yes, are bad. They look like this.

But then the Mirari happened, and made everything strongerbetterfasterharder. After the Mirari, elves looked like this.

Now, I’m not saying these are the best designs for “elf,” because they’re certainly actively intended to be weird and freaky, but I’m still inherently more interested in these people than the humans-with-pointy-ears on the rest of Dominaria.

Mirrodin elves are sweet, though.

Look at that hair. That is NOT hair. That is cable.

Native copper feather

One of the more attractive forms into which copper precipitates from the element charged fluids that ferry it around the depths of the Earth from its source, often in a volcanic system of granitic composition that spits out metal laden fluids in an aureole around the granite. Many of the bigger mines in places like Chile are in fact exploiting the surroundings of magma chambers and plumbing systems from long eroded volcanoes that once exploded on the planet’s surface.

Another gif set from the oscillating chemiluminescent reaction.

On the gifs you can see that moment when we added the hydrogen peroxide to the luminol/sodium-hydroxide/potassium-thiocyanate/copper-sulfate mix. The peroxide oxidizes the copper-luminol spontaneously what emits a bright blue light. After that, the concentration of the copper falls back to nearly 0 therefore no light is emitted. By the time, the copper concentration increases again what means light emission and it starts again, this is called oscillation.

New Material Could Help Clean Up Oil Spills

by Marcus Woo, Inside Science

The Deepwater Horizon oil rig exploded in the Gulf of Mexico five years ago today, killing 11 people. The leak that followed spilled millions of barrels of oil, creating one of the worst environmental disasters ever.

Despite renewed safety efforts, disastrous accidents will almost surely happen again.

During the Deepwater Horizon disaster, cleanup workers used a number of methods to reduce the spill’s impact, including boats that skim the oil off the gulf’s surface, chemicals that disperse the oil, oil-absorbing pom-poms, and even burning. Now, researchers have developed a new potential tool: a high-tech coated mesh that separates oil from water with the ease of a sieve.

“There’s only so much oil you can absorb,” said materials scientist Bharat Bhushan of The Ohio State University. “What we try to do is rather than absorb it, we try to separate the two.”
