Speckled stoneware

Speckled stoneware clay with impalpable grog 0-0.2 mm. Designed for artistic ceramics, it contains melting minerals that develop a seductive surface with dark spots of different sizes and shades that stand out in an ivory-white matrix. Its high grog content provides excellent behaviour during drying and firing. Decoration with transparent glazes is ideal to enhance the vividness of the speckled effect. Available in extruded body (moist form).
