Unfortunately, the glaze on the the handle has crazed causing these pinholes. They are only on the handle and the rest of the mug is perfect!
Handcrafted mugs are made from Stoneware clay. They are glazed and fired at a high temperature of 1200C.
They are approximately 9cm tall X 8cm wide and hold approximately 300ml. Please note, as these are handmade, they are all individually unique and will vary in size and glaze application.
They are food safe and dishwasher and microwave safe.
