This project combines stone clay and cyanotype techniques to explore the transformation of the spiciness of chili peppers from a biological defence mechanism to a multifunctional symbol in human culture. The domestication of chilli is similar to its transformation from a wild state to one adapted to human needs. Wild chilli fruits are small and pointed, and fall off easily when ripe, making it easy for birds to spread the seeds. Through human cultivation, these fruits become larger and the spiciness is adjusted to be more palatable. For chilli peppers, human cultivation became a new survival strategy that ensured their reproduction and spread in diverse environments, where spiciness was no longer their only defence mechanism. It has been integrated and used by various cultures, becoming a unique condiment, medicine, and even weapon. This project investigates how the aromatic components of chili peppers such as capsaicin interact with cyanotype and attaches to hand-moulded clay sculptures, aiming to reveal the complexities between nature and human social development.
