description: I have developed a personal interest in harnessing the power of chemistry and utilizing it directly in architecture. Not strictly through material science but through the direct application of chemistry in the way buildings function. we researched chromogenic materials and their direct application in architecture and reaction/ potency on different material surfaces. a small "particle" of this powder is potent enough to cover an 8.5" x 11" piece of paper. if building facades could utilize chromogenic powder rather than paint, we could revolutionize building facades and save materials/ cut down on material waste.
main strategy: these materials respond to light and are susceptible to change reversibly, expressing changes in their visual transmission, reflection and absorption. Their transparency and coloration also vary dynamically as a response to different stimuli. Colors, hues, iridescences, contours, gradients, ephemeral qualities and transitional stages engender a palimpsest exploring a metamorphic perception and management of form and space.
the exhibition displays the results of experiments with SCRATCH THE SURFACE INK materials. These chromogenic compounds, which have a mechanochromic luminescence property, applied to substrates commonly found in architecture studios have inspired some architectural scenarios that were on display.
Scratch the Surface InkTM was featured in an interactive black light activated graffiti board display as part of the Chromogenic Materials Agents of Architecture Exhibit in the UVA Architecture School April 26-May 2, 2010. BF2AVB ink was provided, along with cotton swabs, rubber septa, burin, and other tools to draw and scratch on different material substrates, including chipboard, black and white foam core, Vyco (vinyl), weighing paper, laser etched plexiglass, and Yupo (polypropylene). This project emerged from engaging discussions and collaborative explorations conducted by Rosana Rubio-Hernandez and Cassandra Fraser.
