Heavyweight deck prism tells a unique story. Translucent aqua green seems like an ocean frozen in glass.
For centuries, sailing ships used Deck Prisms to provide a safe source of natural sunlight to illuminate areas below decks. Before electricity, light below a vessel's deck was limited. Light below a vessel's deck was provided by candles, oil and kerosene lamps - all dangerous aboard a wooden ship.
The deck prism was a clever solution. Laid flush into the deck, the hexagonal glass prism refracted and dispersed a flood of natural light into the cabin below from a small deck opening without weakening the planks or becoming a fire hazard.
Clear, affordable glass was really a development of the last half of the 19th Century. Up till then bottles or other glass products were simply cast or blown in green or brownish glass.
Made of molten aqua green glass. Presented in a wooden gift box.
