A method of photochemical application of gold films on the dielectric surfaces is offered. At this initially by dipping of sample in a solution of gold chloride the sorption layer of the solution is created on the surface. Then, the drying process is carried out under direct sunlight. As the drying of the sorption layer the conditions are created for the formation of monovalent gold chloride having semiconducting properties that allows gold reducing photochemical reaction to take place. Carrying out the process at room temperature in the absence of a reducing agent simplifies a gilding technology. A study of photochemical gilding textile using the scanning electron microscope ISM-6490-LV (JEOL, Japan) is showed that the degree of transition of gold on the surface of a textile is greater than 97%.
