NOVELTY - Manufacture of patterned glass, especially for building solar collectors, solar batteries, and glasshouses, comprises on one smooth surface of pane of glass, covering surfaces with no patterned motifs with paint using serigraphy method; after drying the paint, masking tightly the second smooth surface of the pane of glass; placing the prepared glass pane into a tank with an acid compound; and subjecting to pickling operation to etch out the surfaces not covered with paint for a time, which depends on the desired depth of the patterned motif in the glass mass.    USE - The method is for manufacturing patterned glass, especially for building solar collectors, solar batteries, and glasshouses. It is useful for putting trade and publicity inscriptions on solar collectors, solar batteries, or glasshouses. Uses include but are not limited to providing decorative design for furniture and building industry and as roofing e.g. in stadiums, housing constructions, swimming pools, airports, and traffic facilities.    ADVANTAGE - The method provides glass having increased light transmission, i.e. 90.0-93.0%, achieving an increase of up to 8% in comparison with the same parameters of the base glass, with the indicator of light dissipation in the full radiation range being controlled at the same time and the indicator being freely changeable depending on the use, thus reducing operating costs of other sources of energy; and provides glass surface with variable or homogeneous porosity depending on future use. It improves the decorative qualities because due to the different refraction of dissipation and the different degree of light transmission amounting to over 91.4%, the changing structure of the glass surface creates unique graphical designs, pictures, and inscriptions.    DETAILED DESCRIPTION - Manufacture of patterned glass, especially for building solar collectors, solar batteries, and glasshouses, comprises on one surface of 3-5 mm-thick pane of glass, making a patterned motif of a rough structure made of the glass. On one smooth surface of the pane of glass, the surfaces with no patterned motifs are covered with paint using serigraphy method and then after the paint is dried, the second smooth surface of the pane of glass is masked tightly. The prepared glass pane is placed into a tank with an acid compound and subjected to pickling operation to etch out the surfaces not covered with paint for a time, which depends on the desired depth of the patterned motif in the glass mass.
