Nature as the Artist
Sparkling ice needles, glinting wafts of mist, white hoarfrost – nature is full of fascinating phenomena. Thomas Rappaport is an artist with an eye for them. In his project "giSCHt – melting sculptures" he artistically accompanies a cherry tree on its terminal way. After 80 years of blossoming, coming to red rich fruition, giving shade und being part of the all-terrain microclimate, the artist creates a unique portrait of the tree.
Thomas Rappaport about his art project
"Gischt" in German denominates a natural phenomenon which I want to describe as follows: Wind wafts over the lake taking up drops of water to moisten the trees and anything else which waits at the shore. If the temperature is below zero, this mass of water laden air will slowly create a bizarrely beautiful sculpture in ice.
Water as "art stuff"
I started out as a wood-carver, creating traditional classic wooden sculptures, the ones which are generally put on a pedestal. Over the years, I have discovered the tree as a whole, as a material in itself – for a time I would only see the dead trunks standing there, but now I have finally come to recognize the tree whilst it’s still alive. Some years ago I discovered by chance that my wooden sculptures appear totally different when put into water. Through buoyancy one part of it stays under water, however, it is still visible. Light is refracted at water level and so is the form of the sculpture.
Additionally I re-discovered something: There is the tradition of rafting in order to transport tree trunks through creeks and rivers, even over long distances. In English you call this „water-borne timber“. And if I interpret this expression freely it means „wood which was born from water“. By taking photographs of my floating wooden sculptures („rafts“) underneath the water level these optical refractions and reflections became visible. Thus I started to perceive and appreciate water itself as „art stuff“ to create with.
It inspired me to „look over nature’s shoulder“. It uses heat and cold like a sculptor his chisel. There is even a triple point, where pressure ratio and temperature come together in such a way, that water is a liquid, solid (ice) and gas (vapour/fog) at the same time - well nearly!
All these experiences influenced my giSCHt-project: I sprayed the dead cherry tree with a hot water high-pressure cleaner several times at temperatures below zero, i.e. permanent frost. The entire structure of the tree was to be completely enveloped in solid layers of ice.
The pressure-temperature-diagram presents the transformations into the different states of matter. It shows something fascinating: there is a stage where water can take up all three states at the same time – dependent on ambient pressure and temperature. This is called the triple point.
For his giSCHt-project Thomas Rappaport sprays hot vapour on a dead cherry tree. It disseminates through the air and gently covering the trunk and branches. Hoarfrost evolves. By spraying more and more atomized water onto the tree an ice shield is formed – artistic and impressive. This shield protects the buds of a tree from night frosts which can reach temperatures far below ten degrees Celsius, because under the ice shield the temperature doesn’t go below minus one degree Celcius. In this biological processes are certainly not impaired.
When liquid water boils – this happens at sea level at 100 degrees Celsius – it becomes steam. Cooling down to zero degrees it solidifies to ice. In reverse, ice melts at zero degrees to water. Steam on the other hand condenses at 100 degrees Celsius to water. Finally, there is the phenomenon when ice transforms directly into a gaseous state, i.e. without going through the liquid aggregate phase. This is technically called sublimation. In this case the ice dries out, so to speak. To the contrary, steam can resublime to ice – visible as frost flowers or hoarfrost.
Fog emerges if tiny droplets of water are distributed in the air. When the air cools down its capacity to take up water decreases, which causes water to condensate. Hoarfrost builds up when hypothermic steam transforms directly from its gaseous phase into the solid one, which happens at temperatures below zero degrees Celsius.
Water is life – without water there remains no life
Water exists on Earth in different states and forms. Sun vaporizes liquid water to steam, it can reform as clouds or fog – and recurs to Earth as rain. At temperatures under zero degrees Celsius water starts to freeze and form the solid ice. Glaciers remind us of the last ice age which ended at around 10.000 years ago. On the other hand there is the phenomenon of geothermics: Terrestrial heat warms up the water underground, thus creating hot springs. They leak out of the Earth as gas, in cooler air it condenses quickly to vapour – a state of equilibrium between liquid and gaseous state.
From everyday life we know water’s three states, also called aggregate phases:
In its solid phase water keeps its shape, liquidly it adapts itself to the form of its surroundings, and finally as a gas it fills up completely the space available.

"In his oeuvre, human creativity merges with natural conception, artistic work with god’s creation. He entrusts himself and his art completely to nature, takes on its materials and forces, always led by his long experience and deepest respect. He develops performances with an enormous technical effort and nature in powerful rituals. It is most impressive how then the beauty and powers of nature come into fruition."
