The invention relates to coated glass ceramics containing a coloring additive and a preparation method and application thereof, the coated glass is glass ceramics or glass ceramics containing a hydrophobic and oleophobic composite coating on the surface of the coated glass, and the coated glass is characterized by comprising a hydrophobic and oleophobic layer, a middle layer, a priming layer and glass ceramics or glass ceramics from the outermost surface of the glass, the middle layer is formed by ionic crystals with the lattice energy of 700-3000kJ/mol, and the base layer comprises a compound containing Si-O bonds or a mixed silicon oxide layer. According to the invention, the hydrophobic and oleophobic coating film which is firm, durable and excellent in performance can be formed on the coating film interface of the microcrystalline glass even if few Si-O structures exist, and excellent hydrophobic and oleophobic properties can be generated no matter whether the high-crystallinity glass is subjected to ion
