Georgies - Pioneer Dark W/ Speckles (Cone 5/6) A warm toasty color with a "non-toxic" black frit creating speckles of varying sizes. These Frits add a bit of texture in the raw state, similar to the feel of grog and appear somewhat prickly after the bisque firing.They will fully incorporate into the glaze after firing, but minor coldworking (sanding) may be needed for any unglazed portions of the clay.
