A midrange modified porcelain, CKK6 rides the line between porcelain and stoneware. It gives you beautiful, bright white finishes with less of the traditional porcelain finnicky-ness.

Super smooth slip makes CKK6 a dream to throw. Great for Potters who want to dip their toes into the world of porcelain. CKK6 can be a touch more reactive on the wheel; however, it maintains good stability for making larger pieces, as you would see in standard stoneware. Trimming is unbelievably satisfying; the smooth clay texture means you can kiss unruly trimming lines goodbye. Any unwanted texture can be softened out easily with a damp sponge. 

CKK6 with grog is an excellent choice for handbuilders who want more structure while keeping the delicate look of porcelain. Grog helps create sturdier walls and improves the drying process. As with all porcelains, CKK6 can be more impacted by moisture differences than a typical stoneware. Consider using slow-drying processes; they can be very beneficial for this clay body, especially when handbuilding. 

Fires white at cone 5 or 6. Available with added grog.

To use: wedge wet clay, work as preferred, and fire to ∆ 5. Use with mid-range glazes.
