Stoneware for 3D printing

The popular PRAI, high fire white body with 40% impalpable grog 0-0.2 mm, adapted for 3D printing. Its particular white ivory colour after firing is much appreciated and provides an excellent ware for glazes and colouring oxides. Besides, its characteristics offer an excellent behaviour during drying and firing. Available in extruded body with the ideal humidity for 3D printing. Presented in a practical cylindrical format with double packaging.
