Potters mark their pots if they share the studio space and kilns with other potters. It is a simple and convenient way of being able to find your objects in a large studio community. They use initials, little personalized stamps, shells, etc. Letter C may be an initial, not necessarily a brand.
Some images would help at least to identify the style or other details.
