The 16.15 is a tree-like 16 installation using fifteen pendants and a modular stainless steel armature system mounted to a three tube stainless steel ‘cypress’ base. These trees are designed to be grouped into forest-like assemblies of a variety of different sizes and types, but are strong compositional elements on their own. Installation of these trees is complex and Bocci recommends a structural consultant to assess the viability of the system in the context in which it is to be installed. Installation requires anchoring into either an existing structural slab or a newly built foundation to meet the specifications of the design drawings, including appropriate drainage if exposed to water and remotely mounted LED drivers. 16 is formed by sequentially pouring three separate layers of coloured, molten glass – in varying opacities – on a horizontal plane. Each layer responds to the indeterminate shape of the previous pour to create a uniquely layered whole. Two of these pieces are then attached and illuminated with an internal LED lamp. The finished 16 is visually complex: each separate colour layer is visible through the other layers, with light reflecting along the edges.
