Compare the form of the wells
Count the compartments and look at their depth, shape and relationship to the centre of the plate. Measure the whole piece as well as the available serving area. Decorative similarities can hide substantial differences in proportion, especially when viewing several plates in photographs taken at different scales.
Examine raised and recessed details
Ask for close views of rims, relief decoration and the transitions around each well. These areas can be difficult to assess in a group photograph. Document chips, repairs and surface changes separately for every plate. An appealing pattern should not replace a clear condition description.
Decide how the collection will be used
A wall display can accommodate variation that would be inconvenient in a table setting. For food service, obtain appropriate confirmation of suitability and care rather than relying on the object’s original purpose. Choose a consistent visual thread for the group and retain photographs and dimensions when searching for additions.
