The International Prototype Kilogram, Or Le Grand K

johnson_matthey_kilos.jpg
Caught this on the CBC last night. I always assumed a kilogram is equal to the mass of a liter of water. But it turns out to be messy/tricky/complicated to measure water accurately enough, plus, some scientists decided to change the definition soon after it was decreed, so a kilogram is actually equal to the mass of the kilogram, the International Prototype Kilogram, or IPK, also known in France as Le Grand K. It’s the only unit of measure, says Wikipedia, “that is still defined in relation to an artifact rather than to a fundamental physical property that can be reproduced in different laboratories.”

The IPK is made of a platinum alloy known as “Pt‑10Ir”, which is 90% platinum and 10% iridium (by mass) and is machined into a right-circular cylinder (height = diameter) of 39.17 mm to minimize its surface area. The addition of 10% iridium improved upon the all-platinum Kilogram of the Archives [originally made and adopted in 1799. -ed.] by greatly increasing hardness while still retaining platinum’s many virtues: extreme resistance to oxidation, extremely high density, satisfactory electrical and thermal conductivities, and low magnetic susceptibility. The IPK and its six sister copies are stored at the International Bureau of Weights and Measures (BIPM) in an environmentally monitored safe in the lower vault located in the basement of the BIPM’s Chateau de Breteuil in Sèvres on the outskirts of Paris. Three independently controlled keys are required to open the vault. Official copies of the IPK were made available to other nations to serve as their national standards. These are compared to the IPK roughly every 50 years.

The IPK is stored under three bell jars, and its six sister copies are each stored under two.
ipk_bipm.jpg
The IPK and two other cylinders were manufactured in 1879 by Johnson Matthey, assayers and refiners for the Bank of England. [IPK is the third, KIII.] Johnson Matthey made 40 replicas in 1884, which were calibrated to IPK. 34 were distributed in 1889 to signatories of the Meter Convention for use as national standards. Two of this original batch, K4 and K20, are in the US. K20 was designated the US standard prototype in 1889.
The process and protocols for comparing these replicas to IPK, known as “periodic verification,” have evolved over the years. The BIPM was apparently not so distracted between 1939 and 1946 that they couldn’t develop “The BIPM Cleaning Method,” which involves a chamois, ether, ethanol, and steam cleaning with bi-distilled water. [Considering the Metric system itself was implemented in the midst of the French Revolution, and proceeded even as key scientists were being guillotined, I guess it’s not so surprising.] Models have developed to describe the rate of surface contamination.

What has become clear after the third periodic verification performed between 1988 and 1992 is that masses of the entire worldwide ensemble of prototypes have been slowly but inexorably diverging from each other. It is also clear that the mass of the IPK lost perhaps 50 µg over the last century, and possibly significantly more, in comparison to its official copies.

Given this variation and divergence, much of which cannot be explained, the CIPM [Committee &c.] in 2005 recommended redefining the kilogram as a constant of nature. So far, a suitably stable, reproducible constant has eluded metrologists.
One method is to define the number of carbon-12 atoms in a 1kg cube. Another, part of the Avogadro Project, is to create a single-crystal sphere of silicon, then measure the sphere radius and its internal crystal lattice with interferometry, and then polish it with single atomic level-accuracy to reach 1 kg. A sample is presented here with rather dramatic flair by a master optician at the Australian Centre for Precision Optics:
1kg_silicon_sphere_apco.jpg
Its appearance might look familiar to regular readers of this website.
The human attempt to account for the world through exacting science results in a minimalist object that transcends other Minimalist objects, all while inhabiting a conceptual framework that transcends Conceptualist frameworks.
And I want some. And when I get my kilogram[s], I’ll put them on the shelf next to my satelloons and my photos of the entire universe from the Palomar Sky Survey.

Frosty Myers Winners

latimes, wigwam of searchlights
Before I realized that if I wanted to see an exhibit of a 100-ft silver balloon, I’d have to make it myself, I was still just ruminating on art I hoped/wished someone would make. One of those projects I want/need to see is a re-staging of the Los Angeles Times photo of the panicked air raid searchlights that criss-crossed the sky on the night of Feb. 25, 1942. Six civilians died in that apparent, still unexplained false alarm, and the Times’ caption on the photo above described how the “searchlights built a wigwam” over the city. Wouldn’t that be fantastic?
Well, now I wonder if there is someone to get to do it.
16 Miles pointed to an awesome 2001 Art in America article by Suzaan Boettger on Sculpture in Environment, a pioneering New York City-wide show of public sculpture organized by Sam Green, the director of the ICA in Philadelphia, which took place in October 1967.
The main focus of Boettger’s article is an intriguing and prescient unmonumental work by Claes Oldenberg, and Robert Smithson’s seminal roadtrip article/work, “The Monuments of Passaic,” which [not] coincidentally, he made the day before. And the hook for 16 Miles’ post is the death of Tony Rosenthal, whose Alamo cube still spins where it was shown, in Astor Place. But there are other great details: Oldenberg had first proposed creating a traffic jam; Robert Morris’s jets of steam proposal was considered “too ephemeral.” Isamu Noguchi was still pitching his playground idea [“too expensive.”] Alexander Calder liked to help the Negros. &c. &c.
frosty_myers_searchlights75.jpg
But anyway, Boettger mentions this “a nocturnal event by Forrest Myers, who projected four carbon arc searchlights from Tompkins Square Park.” It’s not clear what they were called, but this description from a 2006 Art in America profile of Frosty Myers explains what these sculptures were:

“Searchlight Sculptures,” nighttime installations of carbon-arc searchlights that were sited at the four corners of Tompkins Square Park in the East Village in 1966, in Union Square in 1969, in a park in Fort Worth in 1979, and elsewhere. The beams tent upward to join at an apex in the manner of a vast pyramid.

Elsewhere included Artpark in Lewiston, NY, where Myers created a Searchlights pyramid in 1975 [see above]. You must admit, it does look very wigwammish.
You may know Myers from such previous greg.org appearances as: being instrumental in E.A.T. and the art/tech collaborative’s ambitious artfest-in-a-mirrored-dome, the Pepsi Pavilion at the Osaka ’70 Expo. And maybe being one of six artists whose work was secretly smuggled onto the moon on the Apollo 12 lunar module.

A Closer Look At Tauba Auerbach’s Pixels

auerbach_paulson_1.jpg
I’d seen Tauba Auerbach’s text- or letter-based paintings before, but I didn’t know about her prints. She did a couple of pairs of prints using pixels last year with Berkeley-based Paulson Press. There’s a black and white set, 50/50, where exactly 50% of the pixels shown are white and 50% are black, and then there’s an 8-color set called A Half Times A Half Times A Half.
Without knowing how or why they were made, I was first drawn to the different resolutions, which she calls “fine” [above] and “coarse” [below]. [And the color ones obviously remind me of Gerhard Richter’s Farben painting series from the early 1970s, which became the basis for his stained glass window in the Koln Cathedral.]
auerbach_paulson_2.jpg
Then I realize they’re aquatints, etchings–Paulson Press specializes in intaglio printing–and not printed digitally, so there’s an interesting transition from digital to physical. And the printing technique itself adds a layer of imperfection to a “perfect” digital original.
Of 50/50, Auerbach said [pdf]:

I was thinking about binary as a language, like binary code for computers, as well as just the binaries within the English language, and how in binary code there’s just zeros and ones.
You have to represent everything, including the ambiguous, with just those two components.

So she’s started introducing randomness. The b/w pixels are randomly placed, but it really pops in the color etchings:

I created three plates. And these three pigment primaries are like the process primaries used for printing –cyan, magenta, and yellow. And on each plate there’s a random pattern of colored squares and blank squares, and they overlap at varous probabilities to create seven possible colors–or eight if you include the white. So, the three primaries, the three secondaries, and then a seventh color where all three overlap, and then the white where none overlap.

So if I’m reading that right, each plate could be printed with any of the three colors. The plates x inks would generate a the number of permutations–though it’d be doubled if the top and bottom of the rectangular plates are reversed.
As I’m typing this, it sounds like a Sol Lewitt, too, an early, exhaustive Lewitt serialization made in the mature Lewitt’s palette. But there are at least 84 possible combinations for each print–if the top/bottom of each plate don’t matter, there are 816–and Auerbach’s edition size is only 30. Sounds like introducing a bit of randomness into the process was plenty. I’m sure her printers were relieved.

July 24, 1973 Was A Tuesday

I was researching a project just now, came across this, and then noticed the date:

ROBERT SMITHSON, 35, A SCULPTOR, IS DEAD
July 24, 1973, Tuesday
Page 41, 227 words

Robert Smithson, a sculptor, was killed in the crash of a light plane on Friday, along with the pilot and a photographer, as they were inspecting one of his “Earth works” under construction on a ranch near Amarillo, Tex. He was 35 years old and lived at 799 Greenwich Street.

Do Tell

Solicitors for the National Portrait Gallery are apparently threatening legal action against a US Wikipedia user for downloading 3,300 digital photographs of paintings in the UK museum’s collection, and then uploading them to Wikipedia. Says Londonist:

All of the paintings are thought to be from the Victorian era or earlier, and are therefore in the public domain. The rather gristly bone of contention, however, is whether the high resolution images of those paintings are protected by their own copyright.

Seems that the NPG is claiming both copyright infringement for its photographs and database right infringement. Neither of these rights currently exist under US copyright law.
Obviously, I’ve been thinking quite a bit latelyabout the issues around reproducing artwork and the incipient loss/cost/penalty when art is transmitted in a copyright culture. It was always my understanding that museums which hold public domain works–which is the vast amount of material in museums, basically everything over 95 years old–tried to control reproduction of the work by limiting access to the work itself, or by requiring contracts for shooting work, or for using authorized reproductions. [Monticello, for example, has an insane, draconian, and expensive shooting policy that practically requires you to hire a gardener to follow behind and refluff the grass where your tripod had been standing.]
According to the NPG’s solicitors, at least, US and UK laws differ on whether a photograph of an artwork has a copyright in itself, something distinct from the artwork being depicted. Should be interesting.

Enzo Mari x Ikea Mashup, Being Mashed Up

I realized I’d been putting off the actual assembly of my Enzo Mari table, daunted by the impending exactitude and fearful of the commitment of actually screwing all the pieces together.
Which seems to fly in the face of Mari’s original “just hammer it together” intentions for the autoprogettazione series.
I knew that without jigs and a flat surface and proper squaring equipment and such, I was invariably going to misdrill something, and then I’d be trying to redrill holes 1/8th of an inch to the left somewhere, and–
The joint that really made me nervous was the first one I’d have to do, drilling a 5/16″ hold through the center of all the side truss pieces [right about where the knot is in this photo] AND through the ends of the center truss, so that I could thread a carriage bolt through, and hold the entire table together properly. Forever.
Rather than risk screwing this up, I decided to piece each truss together with a steel bookend, and then hammer and wood glue enough joints to hold it. Then I’ll drill and screw the major joints after it’s together.
The carriage bolt and wingnut assembly method is a nod to the original autoprogettazione kits of precut wood, which were produced in 1973 by Simon International and sold briefly as the Metamobile Series.
mari_christies_simon.jpg
I hadn’t thought of how much those simple wingnuts changed the nature of the autoprogettazione concept. They’re the difference between project and product.
The Metamobile kits weren’t just precut wood; they were also predrilled. And that required the construction of jigs, the use of some workshop- or factory-grade hardware, and probably even an assembly line, or at least some batch work. In other words, they were exactly what the autoprogettazione series was supposed to not be: mass produced.

Furniture sold as a kit of parts that comes ready to assemble, with just one tool, just follow the slightly baffling instruction diagrams exactly, and voila! Sound familiar? Enzo Mari beat me to an Ikea mashup by about 35 years.

Les Ballons du Grand Palais

The Grand Palais was already the best of the three venues in the world capable of accommodating my Satelloon project–a re-creation of NASA’s Project Echo (1960), the 100-ft metallic spherical balloon which was world’s first communications satellite, and which was also known as the most beautiful and most-viewed object ever launched into space–but now it’s practically inevitable.
Unless someone tells me that the Pantheon or Grand Central Station have already hosted legendary air shows dating back a hundred years…

These photos from Branger & Cie via the Smithsonian show balloons and blimps on display at the 1re Exposition Internationale de Locomotion Aerienne, which debuted in the nave of the Grand Palais in September 1909. They ran until 1951. Which makes bringing back the spirit of the Air Show both spectaculaire et logique!

Verner Panton Vilbert Chair For Ikea



Verner Panton Vilbert Ikea chair, originally uploaded by JForth.

The dates for Verner Panton’s Vilbert Chair run the gamut, but they cluster around 1993.
He created the chair for Ikea, and it didn’t sell for very long–I’ve seen “six months,” “a season,” and “a year”–and apparently, it didn’t sell very well, either.
As you’d expect from Ikea, it’s made out of melamine-coated MDF. I’m not a huge fan, but I find it very amusing to see how Panton fans and modernist furniture aficionados spin a famous designer’s commercial failure on the cusp of his resurgence.
One hack design site gets just about everything about the chair wrong in one, short sentence: “IKEA began a Panton revival when they reproduced his Vilbert Chair in 1994.”
One Dutch dealer says, “Only shortly Sold as Ikea made the Chair from different Materials as Verner Panton Required.”
But the most frequently repeated explanation, is “The design was perhaps too radical for IKEA shoppers and not that many were sold, making them rare to find today.”
and
This chair proved to be too abstract for the mindset of the Ikea clientele…”
Oddly, the Vilbert is not faring much better in its afterlife as a rare, connoisseur’s collectible, either. At auction, one sold for $450 in 2002; an unopened Vilbert didn’t sell in 2003; six sold for EUR 266 apiece in 2006, two didn’t sell for 400 pounds in 2007. Examples for sale online range from EUR275 to EUR450, while the most sensible prices are still in the thrift shop/garage sale range: EUR25 and “Sure, whatever, just take it.”

Richard Prints: Untitled (300 x 404)

Untitled (300 x 404, After Untitled (Cowboy), 2003 by Richard Prince)
I just got my first edition of Untitled (300 x 404, after Untitled (Cowboy), 2003 by Richard Prince) from the printer. It’s a 1px = 1mm version, which came out to be 12 x 16 inches, inkjet printed on aluminum.
Though it’s crazy to feel any sense of accomplishment for an image I appropriated whose fabrication I outsourced, I’m actually kind of stoked. The print looks fantastic, with a graininess that doesn’t map to the supposed pixel dimensions.
When you zoom in on a screen, a pixel is so nice and tidy and square. But unless you’re a mosaicist or a North Korean cardflipping stadium extravaganza director, physical pixels are probably not going to be square. Who knew?
Anyway, since it cost the same to make one as a dozen, there’s an edition of ten, with a couple of proofs. If I had a dealer, a gallery, an artist career, or an idea to have any of the above, I’d probably sell them. I’m sure they’d be cheaper than the Richard Prince.

Enzo Mari x Ikea Mashup, Ch. 6: Ikeaness


Enzo Mari x Ikea – Joinery, originally uploaded by gregorg.

The tile in the guest bathroom in North Carolina was handmade and sun-dried in Mexico, as you can tell by the single square with the artful flaw, a footprint from a wandering dog.
Woodworking aficionados get off on things like grain patterns and joinery, the more intricate the better. So it’s at once surprising and totally not that after spending so much time finishing this wood, I’m starting to dig its industrial qualities, its intrinsic Ikeaness.
Ikea’s IVAR shelving system is made from unfinished pine, but that’s barely half the story. When you start looking closely, you see that even the simplest board is actually made up of several pieces of wood, spliced together.
It’s never the same, either. Each identical-seeming 72-in. post is unique. It’s almost like they piece all these scraps together with this insane, zig-zag scarf joint, into a single, endless piece of wood, which gets extruded, drilled, and cut to length on the other end.
Once you notice these joints–this one is the highest-contrast of the whole pile–your eyes are drawn to them, like learning a new word and suddenly hearing it everywhere.
The shelves are glued up from pine strips, that’s obvious. But was I really so focused on selecting the “right” color ranges that I didn’t notice this string of lozenge-shaped plugs which filled a massive gap in one of the the shelves? I think that will be the table’s dog footprint.

I just finished putting on the second coat of varnish sealer, and now everything’s drying and curing in the basement. The picture above was how the wood sat for a week between the first coat and this morning, stacked on our radiator [I moved it up after about 24 hours when it wasn’t quite cured, and then my schedule got away from me for the week.]

Enzo Mari X Rirkrit Tiravanija

Untitled (Autoprojettazione, 1123 xE/1123 xR), 2004

As I’ve said before, the first Enzo Mari autoprogettazione furniture I ever saw was by Rirkrit Tiravanija. He had tables and chairs fabricated from polished stainless steel, which his gallery from Mexico City, kurimanzutto, showed at Basel and a couple of other fairs a few years ago.
They weighed a ton and cost a fortune–as furniture, anyway; as sculpture, they seemed like a bargain–but they looked spectacular.
Rirkrit hit a zone in his work then where he was re-creating various examples of modernistic furniture and architecture in mirrored stainless steel; there was a ping pong table; several corner assemblages using three Smithson-esque, non-site mirrors; and an entire chrome pavilion in Bilbao. The effect was to simultaneously aestheticize the original and dematerialize the substantial object on display, turn them into non-objects. Which is kind of ironic, since they’re among the most atypically beautiful works the supposedly non-object-oriented [heh] artist has made.

Enzo Mari x Ikea Mashup, Ch. 4: Finish Fetish

ikea_mari_tung_oil.jpg
For the 2002 reissue of his 1974 catalogue, PROPOSTA PER UN’AUTOPROGETTAZIONE , Enzo Mari added “a few technical hints.” I love them, especially the quotation marks, even as I prepare to ignore them a little and end up with something less “belle” than it could be:

…Then, from a purely formal (symbolic) and “instructive” point of view, table tops are “attractive” [“belle”] if they are made by putting several small planks together. From a strictly utilitarian point of view you can use plywood or chipboard.
For the same reasons the constructions are “attractive” if they are left rough, with the saw marks, neither planed nor varnished.

I found this slightly obsessive discussion of finishing solid pine furniture to be quite helpful, if a little daunting. But already, it saved me from myself and helped me lift my wood finishing sights beyond the lying corporate shelves of Ace Hardware:

First, however, a warning is needed: there is zero ‘truth in advertising’ in the finish industry. Absolutely anything can contain absolutely anything, no matter what the label says. There are products out there labelled tung oil that don’t have any tung oil whatsoever in them. Many ‘tung oil’ products depend mostly on phenolic resins. You have to buy from a source that is expert enough to know precisely what is in their products and trustworthy enough to tell you. In Canada, that’s Lee Valley, in the USA, Sutherland Welles.

Sounds good to me.
Sure enough, the extremely helpful folks at Sutherland and Welles guided me toward the right product for the project, a table with a top that will see regular use. I expect I’ll have enough polymerized tung oil varnish and sealer to give the table a good five coats, if not the 10-12 that Sankey prefers.
Meanwhile, I mapped out each piece to be cut onto the Ivar shelf components with blue tape. I plan to cut everything to length, finish the parts while I can reach all the corners, and then assemble the table. And then give it a last coat or two for good measure.
The wood cost $120, the tung oil, $82.

I Salone Mio: Everyday Life Objects Shop

If you’re in Milano–and after all, why wouldn’t you be this time of year? It’s Il Salone del Mobile, after all–definitely check out Everyday Life Objects Shop, an experimental retail exhibition of sorts organized by Apartamento Magazine and master curator/shopkeep Andy Beach of Reference Library. It opened tonight and runs through the 28th.
As it happens, I have an object in the Shop, an edition, actually, which I will discuss later after Andy sees fit to unveil it. Suffice it to say that I owe my mom Ann Orton and her sewing guru friend Pauline Richards a tremendous debt of gratitude. And when I need to get them to fabricate the rest of the edition, I’ll owe them even more.
Stay tuned.
OK, fine, here’s a picture.
