Rock plate with gradient color and weaving effect and preparation method thereof

The invention belongs to the field of ceramic production, and particularly relates to a rock plate with gradient colors and a weaving effect and a preparation method thereof.The rock plate requested to be protected sequentially comprises a green brick layer, a ground coat layer and a protective glaze layer from inside to outside and further comprises an etching glaze layer arranged between the ground coat layer and the protective glaze layer; the etching glaze in the etching glaze layer reacts with the protective glaze in the protective glaze layer in the firing process, so that the protective glaze layer generates a three-dimensional effect of sinking at the position of the etching glaze, and the sinking depth is 0.3-0.5 mm. The depth of the recess generated at the position where the etching glaze is applied on the surface of the rock plate is obviously greater than the weaving texture depth of the existing ceramic plate, so that the apparent three-dimensional effect of the rock plate provided by the inventi
