This sterling sliver Salt Cellar (and spoon) and Pepper shaker was always in my grandparents’ china cabinet. I must admit I never noticed it or asked about its origin when there was someone who could give me the details. My mother inherited it form her parents and I from my parents. Both items are in the form of a walnut — the salt cellar is half a shell while the pepper shaker is the complete shell standing upright. The bottom of the pepper shaker screws off to fill it.
When you think about it it is a much more civilized, not to mention health conscious, way to use salt instead of shaking it and hoping the flow is not too great.
