The invention discloses a novel glaze storage cylinder with a diversification function and a method for improving the performance of glaze slip. The novel glaze storage cylinder comprises a glaze storage cylinder, an overturning mechanism and a base, wherein the glaze storage cylinder is rotatably mounted on the base through the overturning mechanism and comprises a screen device, a screen pushing device and an inlet/outlet; the screen device is movably clamped in an inner cavity of the glaze storage cylinder and partitions the inner cavity into two or more than two spaces with the same section; the spaces are communicated through a screen; the screen pushing device is mounted on the inner wall of the glaze storage cylinder, the pushing end of the screen pushing device is connected to the screen device and provides push-pull force for the screen device, and the screen device can move back and forth in the inner cavity of the glaze storage cylinder under the action of the push-pull force. The invention provides the novel glaze storage cylinder with the diversification function and the method for improving the performance of the glaze slip, the performance of the glaze slip is directly improved in the glaze storage cylinder, and meanwhile, the adverse effects on the viscosity or the flow speed of the glaze slip caused by a conventional stirring device are avoided by the auto-rotation of the glaze storage cylinder; moreover, bubbles in the glaze slip can be efficiently reduced, and the quality of a product is improved.
