Q: This was my great-grandmother’s vegetable bowl. The mark on the bottom is very clear and has the pattern name, Florence, and manufacturer, C. Bros. Co. I’ve been unable to find anything about the manufacturer.
A: We found this pattern on Replacements Ltd. They identified the maker as Cartwright Brothers, a pottery in East Liverpool, Ohio, in business under that name from 1864 to 1924. The pottery made white granite ware and semi-porcelain. They began making semi-vitreous china in 1909.
