Clear plastic bowls display small items atop a low gondola wall. The bowls attached via metal saddle mounts (see inset). Were it my design I would use a mechanical fastening system for the bowl and mount, such as threaded stud, washer and wingnut. But modern adhesives might also do the job. After all they keep space shuttle reentry tiles glues on … mostly.
