This is a guinomi (sake cup) from the late Joseon Dynasty period. It was made with the aim of being white porcelain, but due to the turbulent times of the country, it has this kind of finish. There are cracks (nyu), but they don't "sing" (make a sound). Although many were made, there aren't many pieces that you'd want to spend a lifetime with. With future use, more staining will enter the cracks, and I think it will change into a more beautiful appearance. Diameter: Approximately 7.4cm Height: Approximately 4.6cm As shown in the images, there are glaze chips and shrinkage. Sizes are approximate. The actual item may differ slightly in color from the images. As it is an old item, there are age-related scratches and stains.
