Artist Andrew Boswell is a nationally-recognized expert in the art of crystalline glaze and has developed a level of control and consistency that's unparalleled in the ceramics world. Starting with a Grolleg porcelain, the piece's form is slip cast, then carved and smoothed to further refine its shape. Once dried and fired, Boswell paints a crystalline glaze onto the surface; with the right temperature, the glaze forms crystals, and these crystals form rings due to Boswell's cooling and reheating technique. Finally, each piece is soaked in acid to strip excess metals. The result is a beautiful, truly artful ornament. Due to the nature of the glazing process, each piece will vary slightly.
