Stoneware.

While black stoneware glazes are difficult to master, experienced ceramicists—such as Erich and Ingrid Triller—developed refined techniques to control the depth and consistency of their black finishes. Their expertise in glaze chemistry and firing conditions allowed them to produce sophisticated, elegant black stoneware that remains highly regarded today.

Erich (1898–1972) and Ingrid Triller (1905–1982) were a husband-and-wife team of ceramists renowned for their elegant stoneware creations. They met during their art studies in Germany between 1929 and 1934. In 1935, they established a ceramics workshop in Tobo, Sweden, where they specialized in elegant, precise stoneware pieces inspired by the Bauhaus movement: functionality, simplicity, and craftsmanship combined with modern production methods and avoiding unnecessary ornamentation.

Their studio in Tobo became a hub for producing high-quality ceramics, and their works are now part of numerous museum collections in Sweden. The Trillers' legacy continues to influence contemporary ceramic art, reflecting a harmonious blend of functional design and artistic expression.
