SILKIES are an interesting – and uncommon – genre of pure VESSEL sea glass. Most think pure vessel sea glass is always frosted with smoothed edges but in fact it can also be like the shards pictured here – shiny and smoothed with nary a trace of frosting. Usually, such shards are found in areas where rivers run into oceans or larger waterways. Note collection of Silky shards above. These have no mineral oil or water on them. They are found on the beach looking exactly like this.
