About Deck Prisms: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 provided by candles, oil and kerosene lamps—all dangerous aboard a wooden ship. The deck prism laid flush into the deck, the glass prism refracted and dispersed natural light into the space below from a small deck opening without weakening the planks or becoming a fire hazard.In normal usage, the prism hangs below the overhead and disperses the light sideways; the top is flat and installed flush with the deck, becoming part of the deck. The lens shapes were naturally derived from the process of handmaking the glass on an 'iron' and would have predated the ability to manufacture flat glass. (A plain flat glass window would just form a single bright spot below—not very useful for general illumination—hence the prismatic shape.)Dragonfly of BlueI use quality recycled shipping supplies whenever possible toreduce waste and help the environment.I ship within two business days of receiving payment.
