Immaterial – something that does not exist in the material world, or something that doesn’t exist in the immediate visual world?
Heat has boundaries, it occupies space in a sense yet in another sense it does not. It has limits, and it transitions from hot to cold over areas sometimes as vast and open as a continent, but also over smaller and more defined spaces such as buildings, and even individual rooms within buildings.
Mario Ramiro is an experimental artist who has been working within the bounds of non-traditional media since to late 1970s. He, along with many other members of the artistic community at the time performed “Urban Interventions” in public spaces in Sao Paulo, Brazil. More recently, in the 1990s, he began to look at thermal sculpture in a series titled “Force Field.” This work looked at the ability to create three dimensional shapes of heat using radiant sources that might generate a volume of heat that had specific limits. This transitioned into the desire to see heat, and after moving to Germany he began to use techniques of laser photography to view the movement of heat around objects, and later schlieren photography to view this heat and the objects at the same time.
What is the nature of the volume of heat that creeps from a radiant source? Does it have set limits before its border abruptly meets that of another climactic influence or is it bound more by the physical constraints of an encasing space?
I would like to take a closer look at mapping the volumetric area occupied by heat produced through a radiant source.
