The paper is concerned with the new glass frosting paste and surface morphology of frosted glass area investigated by the scanning electron microscopy (SEM). The frosting by the new paste occurs at a temperature of approximately 3000C and differs substantially from well known processes of chemical glass etching and glass blasting. Important advantage of the new glass frosting paste is the absence in the paste composition of hydrofluoric acid or its compounds.

SEM investigation results of the glass surface structure which is created by the use of the new glass frosting paste are discussed. During the frosting process the system of microcracks and microblocks is formed in glass surface layer. This structure leads to the change of optic properties of frosted glass surface layer which becomes milklike in colour. The SEM-data of the surface structure after the chemical glass etching and the glass blasting are presented in this paper to be compared with the same data of the modified structure.

The next important areas of the new paste use are proposed:
• the frosting of glass and mirror surface by the use of the hand-made method (by brush, squeegee or other suitable tools) and stensils or silkscreen stensil forms;
• the application of frosted glass modified surface as the substrate for following deposition of organic or inorganic compounds and others.
