Session 6:Firing in the Gas Kiln: Focus on Shinos, Thursday Mornings
Shinos are a family of glazes united by similarities in recipes, yet they show remarkable variety in appearance when fired. Depending on iron content (in both the glaze and clay body) and soda-ash content, shinos can range in color from opaque white to orange to smoky greys and black. Surface textures can vary too, depending on how the glazes are applied and fired. In this class, we will familiarize ourselves with Claymakers’ palette of shino glazes; we will also mix an additional high-sodium shino designed to encourage “carbon trapping” (which occurs when surface salt crystals capture soot from the kiln atmosphere during firing). We’ll experiment with how wax resists, oxides, layered glazes, and the firing process can all affect glaze outcomes. A previous introductory clay class is a prerequisite.
