Through a process of "formal schematisation", the collection proposes and represents the reality of simple objects, the geometrical cue elaborating a clear and explicit synthesis between form and function. The Mediumsmall beer glass is the first example of this intriguing use of geometry, taking the rule that the volume of a cone is a third of that of a cylinder with the same height and base. Working with a 1 litre (100cl) capacity cylinder as the body of the beer glass and placing a cone of the same dimensions inside it, Aquacalda have created an dual purpose vessel which holds either 66cl or 33cl. The cone when positioned base-down reduces the volume of the cylinder by 33cl leaving 66cl, the perfect volume for a large continental beer, whilst when flipped over, the cone becomes an ideal vessel for a small bottle of beer.
Adopting the concept of geometric dissection and more specifically the Wallace-Bolyai-Gerwien theorem is the Quadrangolo table, which takes advantage of the fact that two polygons with the same surface area are equidecomposable. This means that the two polygons can be divided into a finite number of parts, two by two congruent. Quadrangolo uses this rule to exist as either a square table accommodating four people, or with some swift re-positioning, a rectangular version which can be used as a table for six.
