This is a gratin dish designed by Masatoshi Saeki, a ceramic artist selected as one of the "10 Designers of the World" by the International Museum of Ceramic Art in Faenza, Italy, who passed away in 2019. It is from the 1970s and is no longer in production. It is a vintage item from 50 years ago. Size: Diameter 17.3cm x 12.8cm Height 4.3cm It has been stored at my parents' house for a long time, but it is unused. I have been careful to store it in a dark place, so there are no noticeable stains or dirt, but there are individual differences. Please understand that this is a vintage item before purchasing. *Due to the nature of ceramics, there are "kannyu" (crazing). "Kannyu" refers to the fine crack patterns that appear on the surface of the glaze due to the difference in shrinkage between the ceramic body and the glaze during the cooling process after firing. This does not affect the strength of the vessel, and has been enjoyed as a beautiful pattern since ancient times. If you are looking for a perfect product like a modern product, please refrain from purchasing. We are looking forward to your purchase.
