The invention relates to a sagger for preparing an artwork in a
ceramic firing process and a preparation process of the sagger, wherein the sagger can improve the artistic value of the sagger and change the use purpose of the sagger. The inner surface of the sagger is provided with a
glaze layer which is the same as
ceramic artworks to be fired. Meanwhile, the sagger is prepared from the followingraw materials in parts by weight: 5 to 15 parts of purple kibushi kaolin, 17 to 25 parts of alkaline stone, 25 to 35 parts of clay, 30 to 40 parts of
quartz, 0.1 to 1 part of dietary alkali, 5 to 20parts of white
feldspar and 5 to 10 parts of aluminum
oxide. Characters or patterns are also drawn or carved on the outer surface of the sagger; in the firing process of the
ceramic artwork, firing ofthe sagger artwork is added, the compounding ingredients of the sagger are changed, the surface of the fired sagger is smoother, and the representation of artistic forms is facilitated; a
glaze blankof the ceramic and a
glaze blank of the sagger are coated with a same glaze, the surface glaze color of the fired ceramic is similar to the inner surface glaze color of the sagger, the anti-counterfeiting effect is achieved, the fired sagger can continue to contain the ceramic and can also exist in an independent artwork form, the value of the sagger is improved, the process cost is reduced, andthus the effect of saving resources is achieved.
