On the end of a long era in printmaking

Niall Ferguson, writing in Newsweek, has this to say about the global supply of copper:

"[T]he key to the copper story is soaring Asian demand. Asians want modern houses with Western-style wiring and plumbing. They want cars. They want electronic gadgetry. So they want copper. In 2005 China accounted for 22 percent of global copper consumption. In 2009 the figure was 39 percent. Try as they may, the copper miners can’t keep pace. And the supply of copper in the world isn’t limitless. Indeed, if the rest of the world were to consume at just half the American per capita rate (1,386 pounds a year), we’d exhaust all known copper reserves within just 38 years."

What does this have to do with art? In printmaking, experienced practitioners know that a copper plate is the most luxurious metal for working with. It's a soft metal, so it's easier to work with than steel or zinc, yet it's much tougher than aluminium, which is cheap in most senses of the word. Plus, you can get a wider variety of plate tone from a copper plate, including the brightest whites. Rembrandt worked on copper plates:
So did Picasso:

And so did I when I first learned printmaking. In fact, it was my love for the etchings of these past masters that led me to printmaking in the first place. Here's one of my 'Circe' prints, which uses the same series of techniques as the Picasso print -- aquatint, scraping, hard ground etching, and drypoint:

So when the global supply of copper disappears, one casualty will be a traditional printmaking material that has been used for more than four centuries. Artists will always find other means to express themselves, of course, but I know that I, for one, will miss holding the copper plate out on the flat of my palm, breathing in the oily smell of the ink, slowly wiping the excess ink from the plate with a cloth held in my other hand, and gradually watching as the etched image slowly emerges from a black cloud, like a photographic image rising out of the developing fluid (another process that has virtually died out!).

Brancusi in Plastic

Artist Mary Ellen Croteau is showing these columns made from recycled plastic cartons and lids in the window of the Columbia College bookstore on Michigan Avenue. They are a playful homage to Brancusi's "Endless Columns", with a serious environmental message for our times:

Mary Ellen also runs a wonderful experimental art gallery in a window space in west Chicago, called Art on Armitage. I will be exhibiting a mixed media piece there during August 2012.

How to etch a linoleum block

Linoleum as a material for printmaking has been used for nearly a hundred years now. Normally, you cut an image out using special gouges similar to woodcut tools, cutting away the lino around the image you want to print. This is called relief printmaking, because if you look at the block from the side, the material that remains stands up in relief from the backing material. You then roll ink with a brayer over the surface of the block, place paper over it, and either print by hand or run it through a press. You can do complex things this way (for example, reduction linocuts), but the beauty of the process is that it is quick, simple, and direct.

A few years ago, I saw some prints that were classified as coming from etched linoleum blocks, and I loved the textures I saw in them. In the last few months, I've been trying to use this technique in my own studio, learning about it as one does these days from websites and YouTube videos. I've also had email exchanges with several pr…

Me Talking About Alexander Calder

In the first years of this blog, in 2010-2011, I created a series of 100 short illustrated talks on art that I called Meditations on Art. There is a page on this blog linking to a complete playlist. I remember, about a year after I completed the series, checking in via YouTube and seeing that one of them had passed 1,000 views. An insignificant number compared to your average viral cat video, of course, but considering I made these little videos mostly for my own amusement, it still amazed me that one of them would get 1,000 clicks (whether they were purposeful or accidental).

Well, I just looked at the stats again, and I am amazed to find that one of these videos, the Meditation on Alexander Calder, has now surpassed 18,000 views. Here it is:
