The dark stain left behind, as a consequence of the heat of my body denaturing the enzyme needed for light production

My thumb pressing on the fabric

The fabric in the dark

The fabric in daylight

This is a unique fabric infused with the bioluminescent bacterium Photobacterium phosphoreum. In the dark it emits an ethereal blue light and I gain a great sense of privilidge being able to grasp its cold light in my gloved hand. The production of light though is exquisitely sensitive to temperature, and as this increases beyond 20 C, light production begins to dim until eventually expires completely. When I hold the cloth tightly between my thumb and palm, the heat of my body causes the light to fade, leaving a very human stain on the fabric. I’m exploring using this as a metaphor, to reflect the temperature changes envisaged with global warming but would of course have to use Silk.
