In the above capture from I Love Lucy Season 1, Episode 4 “Lucy Thinks Ricky Is Trying to Murder Her” we see two porcelain apothecary jars on the kitchen shelf.  The apothecary jars appear in several episodes as set dressing in the kitchen in various locations. I have not found an exact match for the jars on the show but similar ones are seen on ebay such as the example below.
