Arachnophobes look away now! I’ve just been to see the golden orb spider silk display at the V&A – and it is stunning.
There are two items. The woven shawl took four years to complete and is woven from threads twisted from 96 individual strands of spider silk. The geometric design is based on traditional Madagascan woven textiles, known as lamba akotifahana.
Even more spectacular is the cape, which was woven and then embroidered and appliquéd.
The comparison between silk from spiders and silk from silkworms is very interesting. The fibre from spiders is cylindrical in cross section, whereas the fibre from the silk worm is triangular, so they reflect light differently. And silkworm silk contains sericin, which has to be removed to improve the sheen and texture of finished silk. Spider silk doesn’t have to be degummed and is also stronger.
However, spiders can’t be farmed like silk worms, as they tend to eat each other, so need to be kept in individual boxes while they are “milked” (or should that be silked?).
The numbers are staggering – more than a million spiders were used, as it takes 600-1,100 to produce 1g of silk – that works out at 300,000 spiders to produce one square metre. One spider produces around 30-50 metres in 25 minutes, after which it is set free.
The exhibition runs until 5 June 2012.
