Undulae lighting made of bioplastic
Exploration of texture in lighting
Undulae is a series of table and pendant lamps made of cornstarch – based bioplastic tubes. Bioplastic is made from the mixture of cornstarch, water, vinegar and glycerin with particular proportion and mixing process. Bioplastic mixture is spread on a sheet of parchment paper with another sheet on top to make a sandwiched unit. This unitis held with two pipes along the longitudinal edges another inside whichkeep the drying unit in place by gravity.
When the bioplastic is left to dry, the bioplastic’s nature of shrinking creates a condition on parchment paper with a crease pattern in one direction, which in turn becomes the texture of the surface of bioplastic tubes. The longitudinal sides that are exposed to the air also create unique undulating pattern along the edges while drying. The color at the edge is applied with food coloring into the liquid mixture when the pour takes place. There are two types of the application of this bioplastic tubes a s a lighting fixture. One is a table lamp that uses the singular tube standing upright above a disk that contains the light bulb.
The other is a pendant lamp that hangs multiple tubes from a disk above that contains the light bulb at the center. There are two lengths for tubes; one is about 36 cm and the other about 50 cm. The placement and combination of bioplastic tubes for pendant lamps can be rearranged by placing them at different locations of the disk’s holes.
