The Series 87 cluster pendant 19 - 61 pieces by Bocci uses a heated glass mix that is vertically stretched and folded back onto itself numerous times between pegs. As the glass cools, this folding motion (along the grain of the loop) turns air - entrapped using soda water - into microfilaments leading to a pearlescent optical quality in the glass. When on the lights illumination travels down and into the microfilaments creating a unique sunset glow. Compared to other clusters in this collection, these lights do not cascade straight down but rather dangle like a collection of necklaces with radiant pendants. This creates quite the dimsenional and interactive lighting fixture. Ideal for use in your hallway, above your dining table or above your stairwell (where they are guaranteed to be the topic of discussion) the Series 87 cluster pendant 19 - 61 pieces suit an eclectic and contemporary aesthetic. Nineteen to sixty-one canopy options available. Two bulb types available.
