Drag deals with a production process inspired by the traditional plaster dragging technique in wich the plaster is constrained in shape by a profile while hardening. This technique traditionally used to produce ornamental cornices is adapted here in order to serially produce various typologies of objects thanks to a single apparatus. The process results in an infinite variation of shapes, all based on solids of revolution. Multiple sizes of semi-circular shapes are aligned on the central axe of the apparatus, which drags the plaster on top of them. The two halves of the object are then assembled together by using the overload of dragged material.
