What type of piece is this? Painting Share a little about the materials, processes and techniques used to create this piece. I used acrylic polymer based paints in colors similar to the ones on the supply list on a black gesso primed stretched canvas. Using the colors straight from the tube gave a lot of depth to the painting and quite a bit of dry brush highlighted and shaded the pears and pitcher. After completing the work, I used a matte medium to seal and bring the colors and textures together for an unbroken finish.
