Hello to All, Because I ran out out of some chemicals that I use in my typical research, I started fooling around with what I had. I cecided to try one of my "cmyk color separations" on multipal layers of glass, but use only white pigment on each layer. Since I had no white watercolor pigment, I used White Out. The stuff used to correct typewriting errors. (Who still uses typewriters?!) The MSDS lists only TiO2 and 2 kinds of naphtha as the components. I added the White Out to the "Glass Subbing" that I have described on this Forum. It is ,basicly, PVA treated with amino- silane. Tot this I added a saturated solution of potasium dichromate. Coated onto clean glass, dried,exposed and developed in warm water. I have attached two images. They are both of the same 4 layered glass image. One is scaned as a transparency and is a positive image. The other is scaned as a reflective image and looks like the negatice of the other. BTW- The guy in the image is me. Ain't I cute. Ladies ?
