Modernist brutalist ceramic pot 1960s

Beautiful decorative ceramic of the 1960s of brutalist type with thick enamelling in brown tones chiné. Probably dutch origin. The shape is quite strange, a bit like a flattened kettle... Height 10cm for a diameter of 20cm. The raw enamelling is satin, matte and shiny in places with a wide "coulure" on one of the sides that overflows even on the base. I have rarely seen a thickness of enamel such as this. Excellent condition.
