The invention provides a process and equipment for producing a glass painting. The process comprises the following steps of: (a) painting on glass, during which, a selected painting pigment is an inorganic oxide pigment, painting of the whole glass painting is completed by directly painting on the glass surface; (b) low-temperature drying, during which, the drying temperature is less than or equal to 120 DEG C; and (c) high-temperature stepwise baking which comprises the following steps of: (1) flatwise laying a dried semi-product of the glass painting in a hot melting furnace, rising the temperature to between 280 and 330 DEG C and maintaining the temperature for 5 to 15 minutes; (2) then, rising the temperature to between 550 and 650 DEG C and maintaining the temperature for 15 to 25 minutes; (3) rising the temperature to between 750 and 850 DEG C and maintaining the temperature for 15 to 30 minutes; (4) starting to reduce the temperature, and maintaining the temperature for 5 to 15minutes when the temperat
