Concrete and Fashion

Airi Isoda likes to pull architectural influences into her fashion designs. Using materials commonly found in the construction industry, such as Tyvek and industrial-grade felt, she designs minimalist clothing. And yes, there is concrete in her work, such as this necklace of beads. Isoda has a degree in architecture and works in both Los Angeles and Tokyo.

But more surprising is her use of fabric dipped in concrete. To give the fabric flexibility, the concrete surface is intentionally broken. I have seen fabric dipped in concrete before, for sculptural purposes –  but not for clothes that could actually be worn.

Isoda is part of wrk-shp, a multi-disciplinary design collective working in the fields of architecture and fashion.

This work shows off one of concrete's greatest strengths: its ability to remain neutral, to be simply a functional material. It is down-to-earth, and without pretension. And yet it can be used as a metaphor for "material" and encourage the viewer to think about what material means.

Concrete Beads

Often, tools and materials determine a design. I stumbled across this silicone pad in our local hardware store -- a hot plate for pots in the kitchen. It was pale blue and very flexible, divided into open squares of about 5 mm, each hole about 2 mm deep. Silicone is a great mold-making material for concrete, so I bought it not knowing at the time what I would do with it.

First, I was thinking the texture would look great pressed into the surface of a larger concrete sculpture, but then I thought of beads, lots of beads. I sprayed the surface of the pad with a release agent, then mixed up a fairly fine mix of Portland cement and stone dust (1:1), with 10% metakaolin, a bit of black dye and some PVA fibers. This was spread over the surface of the mold, then packed with a small rod into the square spaces, smoothed off, and covered in plastic sheet for a few days. When I pulled the concrete out of the mold, the fibers held most of the squares together, so I used a utility knife to slice them apart. The squares were then immersed in water for about a week.

After the week was up and the concrete was probably 90% cured, I drilled each bead with a .9 mm (.035") metal drill. I drilled from both sides to try and keep the hole centered. The next step was to wet-sand all the surfaces by hand, using a 400 grit sandpaper. This gave a smooth surface to the beads and also got rid of all the surface fibers. To round off the edges (rather than hand sanding such tiny shapes) I tumbled them with steel shot for an hour. When they came out of the tumbler, this is what they looked like among the steel shot:

The plan is to use these concrete beads in some minimal jewellery designs, such as the partly completed earrings below.

Isaac Cordal's little concrete people

Isaac Cordal makes little people out of concrete and them places them in thought-provoking situations in various cities and countries in Europe. You can find them in the street, sitting on rooftops, precariously balanced on a pipe, standing up to their waists in water with a life preserver, or standing in the snow. The figures are made in clay, then a silicone mold is made in which the concrete is cast. Some of the figures are painted some left grey.

Some of Cordal's work is mechanized, but I particularly like the small quiet figures.

Street Art London also has an excellent interview with Cordal along with other photographs of his work. A new book has also just been published about Cordal's work called Cement Eclipses, available from Carpet Bombing Culture.

Pillar of Shame

 Wikemedia Commons

This concrete statue, the Pillar of Shame, is in Hong Kong, and commemorates the 50 people who died in Tienanmen Square in Beijing in the government crackdown of 1989. The inscription reads "The old cannot kill the young forever." In 2008 it was painted orange to raise awareness about human rights in China.

This website has links to a number sites with more information and photographs.
The sculpture, by Danish artist Jens Galschiot depicts torn and twisted bodies. Galschiot was not allowed in to Hong Kong when it was painted orange but approved of the transformation.
