In 1641, Herman Doomer, ebony-worker and frame-maker in Amsterdam, applied for a patent (octrooi) for a method of pressing whale baleen (walvisbalein) into ornamental patterns. This technique allowed repeated, sharply detailed relief designs to be made from molds rather than carved each time anew. The pressed baleen could also be stained to imitate ebony, aligning with Doomer’s broader practice in luxury “black” surfaces and offering a materially inventive alternative to costly tropical hardwoods. Scholars argue that his surviving works underline both the serial precision of the technique and its visual ambitions, with pressed motifs sometimes explicitly discussed as print-derived designs translated into relief.
