This vintage 5-piece set of RRB Co. Roseville Ohio Stoneware Pottery : mixing bowls, ranging in size from 9″ to 5″, is a perfect addition to any kitchen. These bowls are in really good condition considering their age and other sets I have seen. One bowl does have a crack – see picture. Made in America in the early 20th century, these round bowls feature a glossy finish and a beige color with a vintage pattern. Handmade and featuring an impressed backstamp, these stoneware bowls are not only functional but also decorative, making them ideal for all occasions. Each bowl is carefully hand washed to maintain their original charm and beauty.
