Slick Additions by 1882 Ltd. with Queensberry Hunt is a collection of uniquely hand glazed items – a true testament to the skill of the Potter. So many factors make up the pattern of the glaze; from the heat of the piece to the weight of the glaze. The Potter works each piece individually making each item unique. Glaze, like ceramic, has a mind of its own. Made in England. Microwave and dishwasher safe.
