Rather rare work by Gilbero Zorio due to the very narrow and long format. The still is made with paint with some traces of fluorescent phosphorus. In practice, by placing the work in the dark and illuminating it with a lamp, preferably LED, for a handful of seconds and then turning off the light, the phosphor emits a luminescence that lasts a few minutes. And this is the peculiarity of this work by Zorio.
