Contenitore (con segni di fuoco 1), 1986

The number in brackets in the title already reveals something essential: this is not an isolated piece but the first declared instalment in a series – the series of containers through which Cavenago, in the mid-1980s, developed his own vocabulary. What distinguishes this piece from the others in the group are its proportions, and these proportions must be examined carefully as they contain a paradox. One hundred and eighty centimetres in height by sixty in width are the dimensions of a door, a door leaf, or a human figure lying vertically. But the third dimension is just six centimetres. It is a container hung on the wall that almost entirely forgoes its own capacity.

Its placement on the wall is not merely an installation detail: it is the very premise of the work. Hung on the wall, facing the viewer, bounded by a rectangular perimeter, the object takes on the format with which the viewer has had a precise relationship for centuries – that of a painting. It is viewed from a distance, whilst standing still in front of it. The acrylic applied to the surface deliberately reinforces this pictorial expectation. Everything about its external appearance invites the viewer to treat the work as a painting.

And it is precisely this expectation that the work defies. For the rectangle hanging on the wall is not a surface: it is a casing, and something is happening inside it. The nichrom wire powered by the electrical transformer is not merely a luminous mark but an element of dual nature, which produces light at its most incandescent points and generates heat throughout, warming the casing from within. Heat thus becomes a constituent element of the work in its own right, not a side-effect of the electrical device but a sculptural component perceptible through senses other than sight: touch, temperature, and the distance one chooses to stand from it.

A painting is not approached or touched. Here, however, the crucial information is revealed only by drawing near, and reaches the skin before it reaches the eye. The frontal orientation dictated by the format corresponds to a zone of radiation that projects into the room, invisible and measurable only by the body: a six-centimetre-thick layer of material generates a perceptual depth in front of it that none of the three dimensions registers. The container, which as a container contains almost nothing, reveals itself to be full through thermal means.

Hence, in all likelihood, the ‘signs of fire’ of the title, which do not describe a decorative motif but a condition. The casing remains closed; its interior is not revealed to the eye, and what takes place within is revealed only through the traces that emerge on the surface. This is how the containers of those years set out the problem that would run through all the artist’s subsequent work: the artwork retains its contents within a threshold of partial visibility and asks the viewer to play their part in completing it.

The list of materials should be read as a diagram of a system, not as an inventory list. Ceramic fibre is an industrially derived refractory insulator, the material used to line furnaces; lead represents mass, opacity and shielding; steel represents structure, and marks the difference from the other containers in the series, where the casing is made of wood. Here, the artefact abandons any trace of joinery and surrenders entirely to the vocabulary of manufacturing. It is a material vocabulary that foreshadows, in essence, the attention Cavenago would devote for decades to functional rather than decorative materials, taken from industry and reused in the field of sculpture.

Ceramic fibre and nichrome together form a coherent system: the insulating material allows incandescence whilst at the same time containing it, in a balance reminiscent of a furnace reduced to its minimum thickness. The very fact that such a thermal machine hangs on the wall like a painting is, in itself, the gesture of the work.
