The invention discloses a preparation method of a double-opening
ceramic cup. The method comprises the following steps: a, pugging; b, throwing; c, body printing: two bodies which are aired to be semi-dry cover a model and are subjected to
extrusion forming by a briquet press and then subjected to demoulding, two cup bodies obtained after demoulding are subjected to foot-to-foot
butt joint by mudat the bottom, and one or more small holes are formed in the
butt joint part to facilitate exhausting; d, body airing; e,
engraving; f,
glaze application; g, firing: a
ceramic product is firstly put in a sagger, and the sagger is sent into a
kiln for firing; and h, drawing: pattern pictures are drawn on the bodies by under-
glaze pigments, and then the bodies are glazed, sent into the
kiln and fired at the high temperature. The method has the beneficial effects as follows: the method for firing can bond two independent cup models together, integrates attractiveness, practicability and uniqueness and can be used for
drinking wine and tea without affecting taste of users, besides, the raw materials are cheap, the manufacturing cost is low, the process is reasonable, the product qualificationratio can reach 90% or higher, and large-scale production can be realized.
