"The invisible - Line" by Francesco Zorzi is an alternative low tech way of producing monochromatic illustrations.
Boiling water, metal brushes, silkscreen-like frames, lamp bulbs are transformed into new creative instruments, which use heat as their own ink on rolls of thermal fax paper used as canvases. This is a special fine paper coated with a chemical that changes color when exposed to heat. Normally used in thermal printers, adding machines, cash registers, credit card terminals, to print data and receipts via fax, here it is used to produce illustrations and drawings in a different, analog new way.
The 'invisible' it is the element linking together all those machines with Zorzi's own idea of a drawing-line.
In fax machines a single tool (a hidden hot resistance) follows an invisible flow of data creating a multitude of different effects, leaving traces on the paper using heat as ink. It' s a very controlled system in which everything is controlled and the output is meant to be perfect, capable of being repeated over and over again.
In 'the invisible - line' man is acting as a machine.
In this case there's no flow of data to be followed, no multi purpose hidden tool doing everything. On the contrary, a variety of tools has been created and displayed on a production line, each one of them doing a very specific job, each one of them requiring man in order to be used.
Self-designed / self-made tools are used to draw lines and shapes, to leave grayscale traces, to add splashes of color on the white surface.
With no printer, with no color, just the paper as both medium and result.
The process is partially controlled but it's never perfect. Copies are never looking exactly the same, even using the same tool. Flaws are part of this line, improvisation and spontaneity replace perfection and technical accuracy.
Heat, with its shades, is the invisible that becomes visible.
Man, with his tools, is the new drawing machine.
