A microcrystalline glass containing a water-repellent and oil-repellent composite coating layer on the surface, a preparation method and application thereof. The coated glass is a microcrystalline glass or a glass ceramic containing a water-repellent and oil-repellent composite coating layer on the surface, which is characterized in that from the outmost surface of the glass, it includes: a water-repellent and oil-repellent layer, an intermediate layer, a bottom layer and a microcrystalline glass or a glass ceramic, wherein, the intermediate layer is the intermediate layer containing ionic crystals with a lattice energy of 700-3000 kJ/mol and formed by the same, the bottom layer includes compounds containing Si—O bonds or a mixed silicon oxide layer. The present invention can form a firm, durable and excellent water-repellent and oil-repellent coating film even if the coating interface of microcrystalline glass has very few Si—O structure, and can achieve excellent water-repellent and oil-repellent property regardless of whether the high-crystallinity glass has done ion exchange or not.
