Roosje van Donselaar creates sculptures and installations inspired by unknown materials and techniques. She begins each project without prior knowledge of the materials, exploring their qualities and characteristics through an intuitive, hands-on approach. As she works, she uncovers both the possibilities and limitations of the materials.

In addition to this tactile exploration, van Donselaar delves into the historical significance of the materials, drawing on science, myths, legends, and studies of lost civilizations.

Her art blends material strength with symbolic meaning, weaving together factual knowledge, fiction, and cultural heritage to guide audiences from ancient history to future possibilities.
