Thomas Woltmann is a furniture designer whose practice proceeds from a single material: ochre, the iron-rich earth that has coloured human making since the first cave paintings and that Denmark ceased to extract in 1965. Since his bachelor project he has returned to the disused ochre works at Løvskal, outside Viborg, digging the pigment by hand from Jutland deposits laid down by the ice. Colour here is a function of the ground and of the fire. Yellow in the soil, red where it meets oxygen, deeper red when burned, violet at the highest temperatures. In the surfaces and glazes Woltmann builds from it, quantity governs hue: a little turns a tile pale sand, more carries it toward burgundy, so a single earth runs its full register across one object.
The work is made in collaboration with local manufacturers and craftsmen, and it enters the histories of the places it draws on. At Bruunshåb Papfabrik, a century-old mill still running its original machinery, Woltmann spent five months substituting raw and burned Løvskal ochre for the synthetic colour the factory had always used, presenting the results as Fra jord til jord in 2025. Clad in Ochre followed that autumn at Nivaagaard Brickworks. The cabinet of pigments, dyed textiles, glaze tests and old tools assembled under the title Løvskal Ochre won the Danish Design Award in 2025, and he is a current fellow of the Danish Arts Foundation's DUKE programme.
For Vanitas in Use I, Woltmann showed Bird Bath (2026), a basin of hand-glazed ceramic tiles built as an altar for birds.
