Rícino is a series of lamps with an almost incorporeal appearance, made of plant-based castor oil resin. The proposal brings to light the living aspect of the material, exalting its aesthetic qualities and proposing an alternative application to its originally technical use. The project arises from the studio’s interest in natural resins, a research process that began in 2018. In the search for a moldable material with good resistance to temperature variations, the plant-based castor polymer came up. Its thermal stability allied to its visual aspect – with an amber and transparent color – inspired the development of the collection, which has resin as a central element. Developed by the University of São Paulo, it is mainly used in civil construction as a waterproofing agent, or varnish. Characteristics such as its physical-chemical stability, elasticity, and ability to adhere to porous materials make this polymer very efficient in sustainably replacing petroleum derivatives. But close observation can show something beyond this function: when placed against light, the material produces an orange glow, warm and ethereal. From this perception, a study was planned in order to understand the material’s applications, behavior and limits, with the objective of enabling the casting of large portions of resin mass. Over the last few years, several experiments have been carried out to adapt its characteristics and potential for use in design.
