These unique Polish pottery tableware water butter dishes are decorative and practical. In the lower part comes some water which you simply exchange 1 - 2 x a week. In the other half they fill the butter or margarine. The two parts are then placed one inside the other. Due to the evaporation cooling of the water, the butter is suitably cooled and is always spreadable. As the entire Bunzlau range - this dish is also oven-proof, dishwasher-safe and microwave-proof.
