This hand-crafted bioplastic is made from biomass components (wheat starch). The starch is mixed together with water, glycerin and white vinegar, and cooked to a certain consistency, just before boiling. It is then coloured by collected pigments or inks. The drying context (temperature, humidity rate) will define its shapes and textures. Depending on the recipe (quantity of water, glycerine or vinegar), it will take more or less time to dry, usually from 2 to 8 days.
Starch is a reserve molecule for plants and a common component of the human diet. Used in this particular context, it has the property to breathe, digest, mutate and regenerate itself. The bioplastic is a material in between several states and acquires an infinite transformation, constantly changing materiality over time. It can also be reheated and reformed.
Exposed at a high humidity rate, the bioplastic is consequently mutating, breaking, liquefying itself and running. In a stable environment, the matter can also dry out and breach. The sisal (natural fibre from agave) here, creates a structure that prevents the bioplastic to decompose into several pieces and allows it to stick together.
‘Incorporate’ was developed during a residency at Centre d’Art du Parc Saint Léger and was then presented in a group show at MO.CO Panacée.
