Ascheschmelzverhalten
2022
Samples of ash derived from biomass are melted in the laboratory on tiny alumina crucibles at extremely high temperatures.
During this renewed heating process, the ash undergoes vitrification – it sinters and becomes glass-like. The ash of the original plant and biomass material is heated beyond its individual melting point, dissolving on the carrier plate into its natural, elemental structure.
At first glance, the microscopically small sample plates from the Ascheschmelzverhalten analysis appear to show nothing more than colored dots. But through macrophotography, a closer look reveals an unexpected depth within the material. Hidden worlds become visible – each one unique in its color and form.
In their diversity, these miniature landscapes reach far beyond their botanical origin, evoking associations, memories, and dreams. They become symbols of condensed time, brought to a temporary halt in the stillness of glass – the final stage of their transformation.
