It's interesting how many people have told me that when they think of my application process they envision a single cup of whole blood and a paint brush. If only it were that simple. Blood alone can only do so much as a painting material. Like any form of pigment out there it requires something to bind it to a surface. With the hemoglobin in blood acting as the primary pigment, the tonal range and hue variations in my work are a result of reactions to different chemicals. I've found nearly a dozen chemicals that are able to act as suitable binders for the blood by preserving its color and/or adhering it to the surface.
Some chemicals are more favorable to maintain color, while others may dull the color but in exchange allow for more control of the material. The color swatch sample to the left shows one example of how through incremental concentrations of blood with the chemical binder can vary the tonal range and hue results. Applying multiple layers of the same ratio atop of one another can create darker tones, but doesn't show as much of a change for the hue. In addition to the chemicals preserving the hues, the resin coatings also contribute to maintaining the color; especially the UV protective resin.
