The present invention discloses a blue and white color porcelain preparation method, wherein the blue and white color porcelain is prepared by carrying out billet material preparing, molding, firing,
colored drawing and other
processing processes. The preparation method sequentially comprises: preparing a billet material and a
glaze material, carrying out rolling pressing molding on a rolled and pressed mud cake in a
gypsum mold, placing the mold billet into a
chain type drying agent or baking chamber to dry,
drying the green billet after separating the mold and the billet, taking out the green billet after achieving a certain strength, finishing the billet, loading the qualified green billet into a
kiln car
boron plate or gate bowl, carrying biscuit firing in a biscuit firing
kiln tunnel, burning by using
natural gas, carrying out biscuit finishing and
polishing water washing after discharging out from the
kiln,
drying, carrying out
glaze spraying on the biscuit porcelain in a manual or automatic
glaze applying
production line manner, drying, loading into a glaze firing
tunnel kiln to carry out glaze firing, carrying out manual applique,
colored drawing and gold inlaying on the qualified white porcelain, drying, placing into a
natural gas open-
flame burning roller channel decorating kiln to fire, and discharging out from the kiln to obtain the color porcelain. The blue and white color porcelain preparation method has the following advantages that: the industrial production efficiency is increased, the product appearance is beautiful, the
duration time, the degree and the temperature of heating can be well controlled, the finished product quality is increased and the like.
