Solid Waves

The video installation interweaves three geological and cultural formations into a narrative about material cycles and time: Lake Störmthal, the Wimmelburg Schlotten, and fossils from the Muschelkalk formation. In Lake Störmthal, a flooded former open-cast mine, white cloudiness appears through controlled liming: calcium carbonate is introduced to stabilize water quality and pH levels. Seen from above, the artificial lime clouds resemble an echo of ancient rock formation. Underground, the Wimmelburg Schlotten show how water shapes landscapes. Over thousands of years, it washed through the Zechstein deposits, creating valleys above ground and extensive cavities below. The “Tanzsaal” (ballroom), a monumental chamber, connects geological process and human use. Recordings of Muschelkalk fossils point to a shallow sea 240 million years ago. Their images transform petrified life into topographies and reliefs—maps of a geological memory.
Thus, three forms of lime come into relation: the artificially introduced calcium carbonate in the lake, the cavities carved out by water, and the fossils as witnesses of a past era. Lime appears not only as a material but as a medium: it carries memory, marks ruptures, and reveals traces that inscribe themselves into our present.
