One of the three glass designs Toni Zuccheri created for Venini, corteccia or bark glass was impressed with a pattern resembling the gnarled surface of tree bark. Not only was the abstract pattern visualy interesting, but it also served to hide the lightbulbs and to a greater extent, it diffused the direct light the bulbs emitted. Corteccia was usually found on tubular- or ribbon-shaped glass, so the pieces would resemble branches or strips of bark. What's special about the corteccia glass in this chandelier is that the glass pieces are tile-shaped and thicker than the tube or ribbon glass usually used. The thicker glass results in a more  deeply impressed pattern with greater diffusing ability.
 
Venfield currently has three of these five-tiered corteccia glass chandeliers with white powder-coated steel frames. Each has 10 sockets and fits E26 torpedo-shaped bulbs. They are currently on display in our NYC showroom. Priced and sold individually.
