I went to a National Trust property recently that had the dining room table laid with period settings including small vases at each place. I didn't think that looked very authentic so I asked the attendant who told me they were put at each place when dessert was served. I have never seen such a thing and especially have never seen small vases like this for sale (some must still be around if it was common practice). Has anyone heard of this or seen the small vases? They were clear glass about 5 to 6 cm tall.
