Aristocrats were originally the only ones who could afford medicine, often in the form of colloidal silver (the liquid into which silver particles are suspended and was thought of as a cure-all for many different illnesses); could have a considerable number of silver coins and could have worn silver jewelry; and could have eaten off silver plates and used real silver cups and tableware which were later found to shed nano silver particles under a microscope.

How eating utensils came to be known as "Silverware"

Silver is as useful as it is beautiful. A natural antibiotic, it kills bacteria, mold, fungi, viruses, algae and other microorganisms.

People have recognized this benefit since ancient times. Ancient Phoenicians used silver vessels to keep water pure. In the absence of modern refrigeration, sailors then, threw silver coins into their milk to keep it from spoiling on long journeys and wealthy Romans ate with silver plates, knives, forks and spoons to keep spoiled food from making them sick. In fact, historians think that is how eating utensils came to be called “silverware.”
