Q: There are so many instances in the art world where paintings are discovered to be fakes. Do you think this is a potential problem where your work is concerned? Can your pastel paintings be forged?


A: For the record, a little-appreciated fact about my pastel-on-sandpaper paintings is that they can never be forged. To detect a fake, you would only need to x-ray them. If dozens of layers of revisions are not visible under the final pastel painting, you are not looking at an original Rachko, period.
My completed paintings are the results of thousands of decisions. They are the product of an extremely meticulous, labor-intensive, and self-invented process. This is the difference between spending months thinking about and creating a painting, as I do, or a single day. It’s highly doubtful that my rigorous creative process can EVER be duplicated.

Q: What are your favorite subject(s) and media? (Question from “Arts Illustrated”)

A: Here’s the short answer. I work exclusively in soft pastel on sandpaper, using self-invented pastel techniques that I have been refining for thirty-five years. Since 2017, I have depicted authentic Bolivian Carnival masks that I encountered and photographed at the Museum of Ethnography and Folklore In La Paz.

Q: Your work is unlike anyone else’s. There is such power and boldness in your pastels. What processes are you using to create such poignant and robustly colored work?
A: For thirty-three years I have worked exclusively in soft pastel on sandpaper. Pastel, which is pigment and a binder to hold it together, is as close to unadulterated color as an artist can get. It allows for very saturated color, especially using the self-invented techniques I have developed and mastered. I believe my “science of color” is unique, completely unlike how any other artist works. I spend three to four months on each painting, applying pastel and blending the layers together to mix new colors on the paper.
The acid-free sandpaper support allows the buildup of 25 to 30 layers of pastel as I slowly and meticulously work for hundreds of hours to complete a painting. The paper is extremely forgiving. I can change my mind, correct, refine, etc. as much as I want until a painting is the best I can create at that moment in time.
My techniques for using soft pastel achieve rich velvety textures and exceptionally vibrant color. Blending with my fingers, I painstakingly apply dozens of layers of pastel onto the sandpaper. In addition to the thousands of pastels that I have to choose from, I make new colors directly on the paper. Regardless of size, each pastel painting takes about four months and hundreds of hours to complete.
I have been devoted to soft pastel from the beginning. In my blog and in numerous interviews online and elsewhere, I continue to expound on its merits. For me no other fine art medium comes close.
My subject matter is singular. I am drawn to Mexican, Guatemalan, and Bolivian cultural objects—masks, carved wooden animals, papier mâché figures, and toys. On trips to these countries and elsewhere I frequent local mask shops, markets, and bazaars searching for the figures that will populate my pastel paintings. How, why, when, and where these objects come into my life is an important part of the creative process. Each pastel painting is a highly personal blend of reality, fantasy, and autobiography.

Q: Would you describe how you are taking soft pastel in new directions as a fine art medium?
A: I have been devoted to soft pastel for more than thirty years. In this blog and in countless interviews online and elsewhere, I continue to expound on its merits. For me no other fine art medium comes close.
I have developed my own original methods for working with soft pastel, pushing this venerable 500-year-old medium to its limits and using it in ways that no one has done before. I have created a unique science of color in which I layer and blend pigments. When viewers (including fellow artists) see my work in person for the first time, they often ask, “What medium is this?”
