The Flecks + Specks owners are both ceramic artists who work with porcelain and love bright colors. Frustrated by the “sand” color of manufactured grogs, they developed a grog recipe that allows bright grog colors at all ceramic firings temperatures. Flecks + Specks Grog adds color, texture, and durability to all types of clay. Flecks + Specks Grog is available in an ever-changing palette of colors and five sizes suitable for any method of working with clay.
