Thank you for viewing! I'm selling this to organize my belongings! Height: 20cm x Maximum Width: 17cm x Mouth: 4cm "Oil Spot Tenmoku" is a ceramic technique that developed in China during the Song Dynasty. It is characterized by silver speckles on the surface of a black glaze, resembling droplets of oil that have splashed. These speckles are formed by the crystallization of iron contained in the glaze, which is exposed to high temperatures in the kiln. Due to the mysterious beauty created by chance, it has been treasured since ancient times.
