For the painting, I painted a triptych scene of a sunset in the traditional, imprimatura painting method on three, 48’’x72’’ canvases.  First, I primed the canvases with gesso, let it dry, and then sanded the canvases so that I was working on a smooth ground.  Next, I painted a color underpainting with oil paint diluted with turpentine.  The underpainting served as both a general sketch and established the value and color relationships in the final painting.  After the underpainting dried, I painted over it with thicker paint, diluted with linseed oil instead of turpentine.  In this final layer, I went in with much more detail and smoother paint, creating a more realistic and luminous image.  

The second step of the project was to create different types of glaze that are reactive with ultraviolent light. Various compounds were tested, but the most reactive were used to create the glazes. There were issues with quinine sulfate in getting it to dissolve in a nonpolar solvent to apply to the nonpolar paints and oil. There was also an issue with coumarin because once the compound was in a solvent it would quench the compound and make it unreactive under ultraviolent light, but upon addition of acridine orange the compound would be reactivated, yet it produced a similar color to fluorescein. Upon treatment of patman[1] with coumarin, the compounds no longer glowed under ultraviolent light.  The compounds used for the final glazes consisted of rhodamine, fluorescein, patman. The compounds were fist dissolved in either N, N- dimethylformamide or dimethyl sulfoxide, then added to linseed oil.  Upon research the different compounds are reactive under different wavelengths specifically, rhodamine is most reactive under 550-700 nanometers (nm), while fluorescein is reactive under 490-510 nm, patman is reactive under (#). Hence the different reactivity under different wavelengths will allow the creation of dimension in the image when shown under UV light. Once the oil paint dried completely the glaze were applied to create a glowing image.
