    Patterned float glass is manufactured by locating in contact with the float ribbon, while it is hot, a shaped molten body of a material for modifying the glass surface. The configuration of the molten body is progenitive of a pattern to be introduced into the glass and ionic migration is engendered electrically between the molten body and the glass in a sequence of defined time periods to produce a pattern of modified glass in the ribbon surface. The pattern is formed by switching electrical current supplied to the molten body in sequence while the glass is moving relative to the molten body. The supply may be direct current, alternating current or rectified alternating current, and, in all cases, the switching is an enforced switching of the supply current between different current levels, and is not, for example, merely the result of the alternating current itself when such forms the current supply. In addition, this method of manufacture may be applied to non-float glass operations, where the glass is not supported from below by a molten bath which serves as the cathode.

      U, I The invention relates to the production of sheet glass. A known method for the continuous production of surface-modified glass by moving over the surface of the molten metal of the glass ribbon that contacts its upper surface with a fixed mass of the melt under the current-carrying plate l. The disadvantage of this method is the impossibility of obtaining a decorative pattern formed in the surface of a glass ribbon. The aim of the invention is to obtain repetitively imprinted prints from images with clear boundaries. The goal is achieved by the fact that according to the method of continuous production of surface-modified glass by moving a glass ribbon on the surface of the molten metal that contacts the upper surface with a fixed mass of the melt under the current-carrying anode plate to which electrical current is applied, the bottom surface of the current-carrying plate has the form of the imprinted image, and the current is supplied to it by rectangular pulses, the intervals between which are sufficient to form a moving clear glass ribbon prints the melt surface, wherein movement of the glass ribbon is less than 1.25 mm the time duration of each pulse. Moreover, the length of the mass of the melt along the glass ribbon is 50 mm. FIG. 1 shows a device for making glass that implements this method; FIG. 2 - the same, with the cover removed, top view} in FIG. 3–9, shaped plates with different patterns; plan in FIG. 10-13 the same, top view; in fig. 14 — rectangular anode pulses, feeding Mbiej onto a shaped plate to obtain a pattern. The method of continuous production of surface-modified glass is carried out as follows. . In the bath 1, filled with molten metal 2 (figs. 1 and 2), having a specific gravity greater than the specific weight of glass, and closed by a cover 3, glass mass 4 is fed, which moves along the surface of the molten metal 2. Inside the bath 1, a protective the atmosphere is a mixture of hydrogen (10%) and nitrogen (90%). This mixture is injected through the nozzles 5, and the removal takes place through the openings b and 7 in the end walls of the bath 1 and the cover 3. Through the opening 7 there is also a discharge of glass 8 from the bath 1. Inside the bath 1, across the internal cavity, there is an electric guide bar 9 mounted on which, using a bracket 10 of electrically conductive material, a current-carrying plate 11 is fixed, shaped to fit the contours of the design to be applied to the glass tape 8 (Fig. 3-9) . The gap between the bottom surface of the current lead plate 11 and the upper surface of the glass band 8 is equal to 6 mm and is filled with a mass of melt 12, for example, a copper-lead alloy that sticks to the current lead plate 11 and repeats its shape. Rectangular anode pulses (pulses can have, for example, the shape shown in Fig. 14 and corresponding to the figures on the glass ribbon shown in Fig. 13) are fed through the electric guide bar 9 and the bracket 10 to the current-carrying plate so that the electric current passes from the mass of the melt 12 ribbon 8 glass to the molten metal 2. Due to this, ion migration (for example, copper and lead ions) occurs from the mass of the melt to the surface of the glass ribbon 8, forming a print of the corresponding color. Molten metal 2 is connected to the power supply circuit by means of electrode 13 lowered into it. The intervals between the pulses must be sufficient to form on the surface of the moving glass ribbon clear prints of the surface of the mass of the melt 12, and these prints can be located separately from each other and abut or partially overlap each other, but always have clear boundaries. The movement of the ribbon. 8 glass during the duration of each pulse must not exceed 1.25 mm. The length of the melt mass along the glass ribbon 8 may be 50 mm. The temperature of the glass ribbon at the installation site of the current lead plate 11 is about 750 ° C. The color of the prints on the glass ribbon is selected by changing the metals that make up the current-carrying plate and the mass of the alloy, i.e. using as the mass of the melt alloys of various metals, as well as by changing the current power and composition of the protective atmosphere. The invention can be used to make glass products, such as model glass sheets or molded glass, for example, building glass that has a V-shape. In addition, the invention can be used to process glass products.
