A lamp shade fabricated and dyed from renewable biomass sources, showcasing the beautiful potential of sustainable bioplastics.

The Verlumina light shade consists of 12 modules molded out of a gelatin and agar bioplastic and dyed with chlorophyll extracted from local California grass.
Each module of the light consists of:
2g agar agar, 15g gelatin, 3.75g glycerol, 75mL distilled water, and 18mL grass pigment.

There are 12 modules in total, and each module took around 36 hours to create from pouring to the dry product. There are individual photos from each stage of production and assembly, from boiling the raw ingredients, draping the flat sheet, and stringing the final modules together.
After a long process of research and experimenting with different proportions of ingredients, it was determined that a combined gel of agar and gelatin resulted in a material with the best properties.
The two best methods found for controlling the form of the temperamental bioplastic
Chlorophyll extracted from locally grows grass was used to colorize the bioplastic.
The light was designed to showcase the potential of bioplastics, as it includes modules that are repeatable, yet entirely unique in their organic draped form.
