Painting on Plaster: Material as Conversation
with Laura Ralls Duprey

July 21-22 • 11a-2:30p

$250

This intensive six-hour workshop invites artists to explore the expressive possibilities of oil painting on an absorbent plaster ground. Beginning with the creation of the surface itself, participants will learn how to build, refine, and prepare a mineral-based ground that becomes more than a support-it becomes an active collaborator in the painting process.

Working with traditional oil painting techniques adapted for highly absorbent surfaces, we will investigate transparency, opacity, glazing, scumbling, and the subtle luminosity that emerges when pigment is absorbed into plaster. The workshop also examines the relationship between surface and image, where texture, erosion, and the physical memory of the material contribute to the finished work.

Drawing from historical painting practices, while embracing contemporary mixed-media approaches, this workshop considers the surface as a site of inquiry-where painting becomes a conversation between artist, material, and time.

Designed for experienced painters and serious artists, this workshop offers both technical knowledge and a deeper engagement with the poetic potential of plaster as a painting medium.

Participants will leave with prepared panels, painted studies, and practical methods for incorporating these processes into their own studio practice.
