A process for the distribution of a powder for coating glass, whereby a regular, homogeneous coating of uniform thickness is formed, wherein the powder is converted into a metal oxide or oxides upon contact with hot glass, which comprises spraying a powder onto said glass, wherein said powder comprises: (a) a composition which is capable of being converted into a metal oxide or oxides upon contact with hot glass, and (b) a water-repellent, anhydrous product having a base of finely-divided slica. The product with a base of finely-divided silica is added in the amount of about 0.5 to 5%, by weight, based on the total powder weight.
