THYSIA
Material research

In ancient Greece, before every meat cooking, the bones were offered to the gods. The bones, the immortal part of a being’s body, were called ‘The God’s Share’. This ritual was called the Thysia. But where have the bones gone now? How does our meat-consuming society dispose of it? 
Bones represent 32% of the weight of cattle, with a total of 7.5 billion tons produced each year. Bone meal is the main product made from the bones, but since the dramatic ‘mad cow disease’ health scandal, it seems to be banned and forgotten. Bone meal is the main ingredient for pet food in the U.S. and a really popular soil fertilizer. But why do we keep this resource far from sight? Why should the popular mindset think of it as dirty and dangerous waste? Biomimetism of bone structures is a really promising technology that could shape our future, but what about the resource itself? Why don’t we invite it in our lives? In our furniture?

The design was inspired by the concept of "Sacrificial Architecture". It features the classical elements that signify that a monument has a sacrificial function: a curved plate frames by elevated corners. The chair is modular, with 4 legs slotting in the seat, to underline the monolithic dimension of the chair and engage in the erection of it.

Material & Process

The chair is composed of 70% of bonemeal and 30% polyurethane. That gives a volume of 10 kgs of bones inside the furniture. The bonemeal was sourced on mainstream gardening shop as waste bonemeal is commonly used as a fertilizer although it's not commonly known. Bonedust was removed to keep only structural chunks of bones.

The mixture of bone and resin was casted in custom made molds.
