Coffee cups, dinner plates etc. Don't put anything like that directly on the surface, use a coaster or a place mat under it otherwise you will mark the table.Organic items should be fine as long as they are totally dry. So dried flowers are ok, but fresh flowers would both rot underneath the coating, as well as potentially cloud the surrounding epoxy through moisture contamination.
