Abstract
A curved glass and a preparation method is provided. The preparation method for curved glass includes: melting a glass batch into a glass liquid, and clearing the glass liquid; introducing the cleared glass liquid into a mold cavity with a preset shape, and forming, by using a compression molding process, a glass product with a shape corresponding to that of the curved glass, where a size of the glass product is greater than a size of the curved glass; annealing the molded glass product; and processing the annealed glass product into the curved glass based on the shape and the size of the curved glass.
