This stand, promoted by the Institute of Ceramic Technology in Castellón for the CEVISAMA fair of 2017, consists of the construction of a pure trihedron placed so that its bisector is vertical and its vertex at the very top. The sides of the trihedron are defined by an orthogonal grid of ceramic pieces. In turn, the latticework of ceramic pieces is supported by a thin grid of steel tubes of circular section that make up the structure as a whole.

It is worth noting the difficulty of maintaining the slenderness required for the structural tubes in order to make the perception of the sides of the construction literally understood as the sides of a trihedron. This entails the localized use of a grinding system and a careful study of the mechanical capacities of the different types of knots.
