2021 Alexia L. Rosoff 1-Day Workshop

Painting on metal is quite an old process, used by oil painters for centuries. Pastel painters can also adapt to using metal substrates, and the results can be literally illuminating as the metal reflects light through layers of pigment! The rigidity of modern aluminum composite panels can be an advantage for the framing and preservation of pastel paintings. But it can be tricky to get the dry pastel medium to stick!

This workshop will introduce participants to painting on aluminum panels, primarily in pastel but utilizing a range of underpainting mediums. Artists will learn how to prepare panels to accept pastel, how to handle the reflective surface, how to layer without compromising adhesion, and how to finish and frame metal panels. The morning session will talk through these aspects of the support and demonstrate the process. The afternoon session will give artists a chance to try it out themselves, including tips for getting started and troubleshooting, getting in-process feedback, and a final critique.

Materials needed:
- AlumaComp unprimed aluminum panels are available through Amazon in a range of sizes. I recommend buying one or two of the smaller sizes, such as 10”x10” and 11”x14”
- clear gesso/primer or acrylic pastel ground or fine pumice gel (Golden) - sandpaper or sanding block, 150 grit - 70% alcohol
- plastic scraper or rectangular scrap of mat board, about 3”x4”
- workable fixative of choice
- India ink (waterproof drawing ink, like Speedball or Higgins)
- brushes, rags, old toothbrush, other tools of choice
- underpainting mediums of choice: watercolor, acrylic, pastel and alcohol (oils are wonderful on metal, but take too long to dry for the purposes of this workshop)
- any and all soft pastels you’d like to try, including Pan Pastels - sketches and reference photos
- masking tape, easel…all your normal preferred painting tools

Note: Since aluminum is such a reflective surface, lighting can be a really big deal when painting on it. I recommend daylight neutral lighting with diffusion, such as a frosted compact fluorescent or OttLite. If you find that your light source casts too much glare on your panel, using a field umbrella or diffusion frame can help. I don’t recommend painting on reflective aluminum outdoors…plein air is tricky enough without adding additional complications! (Of course, you can eliminate the reflective surface by coating it with white primer, in which case it’s just a rigid acid-free panel like any other.)

Pastel Painting on Aluminum

Alexia Rosoff Wilber

Like many artists, I started out drawing and doing crafts as a kid. I became involved with theater tech crews in high school and college, which led to doing set design and scene painting for summer stock theater. I studied art history and studio art at Williams College, where the curriculum emphasized learning to see and describe art thoroughly and carefully, along with academic drawing and painting foundation skills. After college I ran an equine rescue and rehabilitation program, then returned to art by taking courses in communication design and digital drawing and printmaking at Massachusetts College of Art, and learning digital filmmaking with the New York Film Academy. I then earned my Masters in Visual Media Arts at Emerson College in Boston, and worked on numerous shorts and several feature length films. I began teaching drawing and painting in 2009, and I currently teach art classes with NOA Gallery’s School of Fine Art in Groton, MA, and private lessons and portfolio development through Arts2You in the Greater Boston area, and Lessons.com. I am a frequent guest instructor at The Winsor School in Boston, teaching popular workshops on color theory. My art is represented by NOA Gallery at The Groton Inn, http:// thegrotoninn.com/art-gallery/.
