~What is Sea Glass? – A piece of broken glass undergoes a dramatic transformation on its journey to become sea glass. Once sharp, the shard’s edges gradually smooth by tumbling against rock and sand. Over years water leaches out lime and soda from the glass, leaving a frosted surface where it was once shiny and translucent. This process is called hydration. Some pieces even have pit marks and other patterns in the surface, evidence of their traumatic metamorphosis in the sea. Sea glass qualifies chemically as a mineral gem.
