Since the introduction of CAD drawings everything has been easier and more precise, but simultaneously more rigorous and rigid. What could never have been possible by hand can now be done with digital drawings. Even the most complicated forms and daring joints have become simple.
These are the More than good errors, sought not to make mistakes but to stimulate the search for fresh forms and slight distortions, minute misalignments, missing symmetries and so on. Because making mistakes also means searching when the answer is not clear; it means wandering in order to arrive. Error as the spring of composition can give rise to more surprising, sensitive and exciting objects.
The technique, dating from Etruscan times, is called bucchero. Using dark grayish clay, it is done in three exclusively manual phases. The piece is worked on the lathe, smoothed with boxwood sticks to polish its surface and baked at a high temperature.
The evident imprecision’s in the showcases are not only deliberate in their structure, but actually pursued with great effort, for they are very difficult to achieve. The attainment of slight obliquities entailed the use of advanced manufacturing technologies such as laser cutting and other numeric control systems normally adopted to get straight and absolutely regular lines. We had to examine them so carefully and to understand them so thoroughly that we could bend them to the accomplishment of our own more than good errors.
