Here we have a handsome Shino ware guinomi (sake cup) made with buff stoneware. There is ironstone colored stylized flower on a thick cream colored glaze. On the base of the cup is a mark that purports to be the impressed mark of Rosanjin on base – however, the signature is a Fake. Many examples of fake Rosanjin ceramics have been on the market for years because of his fame and special place in the world of modern Japanese studio ceramic.
The Guinomi measures 2 3/8” diameter at top by 1 5/8” diameter at base by 1/3/8” high. It is in a signed tomobako box. The calligraphy on the top of the box has been translated as – “1) upper right: Shino - 2) Lower right: Guinomi (the type of cup) and 3) name of artist or maker: The first word is Hei, then seal of Zo. We have no idea if the box is the original that came with the cup. It is in excellent condition with no cracks, chips or restorations. We date it to the Showa period, circa 1950s-1970s.
Event though the guinomi bears a fake Rosanjin mark, it is still a very nice example of classic Shino-ware. Shino ware (Shino-yaki?) is a type of Japanese pottery most identifiable for thick white glazes, red scorch marks, and texture of small holes. It is one of the Mino styles from the late 16th century. Like other Mino wares, the Shino style is based on older Seto with changes to shape, decoration, and finish. Forms are usually squat and cylindrical, thick but lightweight. Dishes, bowls, and tea utensils are most common. Pieces can be grey, red, or white, painted with iron oxide or decorated with glaze. Firings of Shino tend to be of lower temperature for a longer period of time, and then a slow cooling process. These conditions do not allow the glaze to melt fully, and the result is a thick glaze that often has a crawling pattern.
