Stephanie decorated this porcelain plate using Amaco Velvet underglazes on both unfired porcelain and touched up on bisque (left image). She over-painted Amaco HF-9 Zinc-Free Clear (at least 3 coats in the center to make it pool into the recessed parts of the image, so it is flat to the touch like émail ombrants technique). The plate rim is a shallow bas-relief so two coats of clear were sufficient there. She fired it to cone 6 (right).
"Émail ombrant" (French for “enamel shadow”) is a pottery-decorating technique developed in France in the 1840s (at the Rubelles factory by Baron A. du Tremblay). Designs were etched or stamped into the pottery and a transparent colored glaze applied thickly enough to re-level the surface. The varying depths produced colour highlighting. The design appears shadowy, hence the name. Stephanie calls these plates “Girls on the March”, they were inspired by parents who supported their girls with dynamic signage at the Boston of “Women on the March” rally in 2017.
This terra cotta sculpture, called “HOPE" was made at the studio of Stephanie Osser, a collaboration with my former student Jamaal Eversley. With Covid, Jamaal had to finish it with acrylic paint. HOPE was exhibited during the 2 months of the Boston Exhibit called “ Real Friends” summer 2020.
A ceramic compound meant to be applied to green or bisque ware and covered using a transparent overglaze. There are good reasons to make your own underglazes if you are in production.
