A lichen is a symbiosis of a fungus and bacteria or algae. About 20,000 species have conquered a wide variety of habitats. kombuτέχ is generated by Acetobacter xylinus which excretes fine fibrils of cellulose.

Yeasts (Saccharomyces) decompose pentoses, feeding the acid bacteria with sugar alcohols.
In a specific pH range, the fungus grows in sprouting chains around the bacteria, sealing it off from intruders and aerating the lichen.
There are other symbionts like Acetobacter gluconicus, Schizosaccharomyces ponbe, Torula, Pichia fermentans.

The lichen is floating on top of the substrate, right where the elements water and air meet.

The alga arises through the mushroom from the water.

The tannins from the tea make the cellulose condense into a scoby on top of the substrate. Without tea, kombucha becomes a glassy jelly.

Adding siliceous earth into a tealess kombucha, filaments will grow, reaching from the sediment at the bottom of the container up to the surface (Ascending light process, Gestaltbildeprozess).

Those filamental tubes hold crystals of siliceous earth in their core.

It is fascinating to paint on kombucha membrane with glow in the dark color. It is like painting with light onto bronze or color negative film.

This figurine was made in 1997 from white clay and is still in unfired state. In 1999, the eye was painted with glow in the dark color, it was clothed in kombucha membrane and coated with latex.

In the guestbook of Europe's first Body Worlds exhibition in Mannheim 1997, I left my notice of regret that no lampshades made from human skin were available in the souvenir shop.

maks is a collage from 1999, inspired by Maksymilian Kolbe and the painful awareness of pop culture instrumentalizing sacred domains.

The original object is lost and very few images remain. The skeleton was painted with eight layers of phosphorescent lacquer actively glowing through the skin.

These experiments date back in 1999. A decade later I found others working with this organism in the sphere of art, which encouraged me to publish my experiences.

“When you dry it, though, it goes translucent, and it’s like dried human skin. So that was the motivation to use this material for talking about racism.”

“My art is not made to last, but to intrigue my public and question the role of art in contemporary society.”

“The skins remain alive in organic stasis and will regenerate if returned to the feeding solution.”
