Measure each type of glass
Record total height, bowl width, opening and base dimensions. A collection photographed together may include several sizes or later additions. Group the pieces by shape before comparing condition. For a dining project, consider how the glass sits beside the chosen plates rather than assessing it on a shelf alone.
Inspect rims, stems and feet
Request detailed photographs of the rim and the points where parts join. Ask for an individual description of chips, scratches and repairs. A low-resolution image with strong reflections can conceal flaws. Differences should be listed for each example, not covered by a single claim about the whole group.
Plan storage and replacement
Establish whether the pieces suit the intended handling, washing and storage routine. Do not infer compatibility with equipment from appearance. Keep a measured reference for future sourcing and define acceptable variations. Restaurants benefit from knowing which glasses can be mixed within a service and which are reserved for a particular decorative setting.
