Prior to first use, all pieces should be washed by hand in hot soapy water, well rinsed and allowed to air dry. To maintain the integrity of the pieces (i.e., colour, glaze), dishwasher use is not recommended. The base of jugs, mugs and vases may initially sweat. This is normal, and will decrease over time. Please protect delicate surfaces that may be affected by water marks. Hand wash recommended.
