Workshop Overview

Choosing between porcelain and stoneware, participants will learn how to create texture and contrast on slabs of clay. Using the slabs, forms, and templates, we will hand-build lidded vessels along with the addition of sculptures as knobs for the lids. Participants will work with sodium silicate for texture, colored slips and inlays for contrast, and with underglazes for brushwork decorations. Pieces will be bisque fired after the workshop with participants returning at a later date to pick up their work. Bisque firing is offered for zooming participants if they can get their pieces to Sitka Center.

About the Instructor(s)

Jeff is a retired science teacher turned studio potter. Creating, experimenting and playing with clay for 23 years, he is a thrower and hand-builder. Jeff has taught ceramics classes and workshops at Oregon State University and in his own studio near Philomath, Oregon. His focus is on vessel forms with surface textures along with decorative slips and inlays. Lids with sculptured knobs are often included. Enthused about atmospheric firings, he uses a soda/gas kiln and typically fires pieces more than once.
