The invention discloses a gray coated glass and a manufacturing method thereof. The gray coated glass comprises at least two layers, the front layer is a glass plate; the second layer is a film layer attached to the air surface of the glass plate, the film layer comprises two metal oxides of cobalt and manganese, and further contains the following metal oxide At least one of the substances: zinc oxide, aluminum oxide, zirconium oxide, copper oxide, iron oxide, chromium oxide, magnesium oxide. The film layer has a thickness of 40 nm to 80 nm. The gray coated glass is pure in color and can replace the body-colored gray glass. The manufacturing method adopts the online high-temperature pyrolysis spraying method, which is completed in the production process of the float glass. The method fully utilizes the heat of the glass plate itself, and causes the metal compound in the spray solution to be pyrolyzed, oxidized and deposited on the glass plate. The surface forms a film layer, and the method realizes continuous production, thereby improving production efficiency, reducing production cost, and saving energy. The gray coated glass produced by this method has a light transmittance of 20-65%.
