A method and apparatus for manufacturing patterned glass sheets. In certain embodiments, the resulting glass sheets have a pattern defined therein which is designed so as to simulate conventional glue chipped glass sheets or antique glass. A heated glass ribbon exits a furnace or melter and proceeds through a nip defined between opposing rollers. Pressure on one or both of the rollers in the direction of the nip, combined with a glue chipped simulating pattern or antique pattern defined in an exterior surface of at least one of the rollers, causes the pattern to be transferred from the roller(s) into/onto a surface(s) of the hot glass ribbon. After being patterned, the glass ribbon is annealed and cut into a plurality of different sheets.

1. A method of manufacturing patterned glass sheets having a visual appearance simulating an appearance of antique glass, the method comprising:providing a furnace or melter;providing first and second opposing rollers which define a nip there between, and providing at least one of the first and second rollers with an antique glass pattern comprising a plurality of intersecting ridges of different lengths defined in an exterior surface thereof, wherein at least some of the ridges intersect one another at angles of from about 5-80 degrees;a ribbon of glass exiting the furnace or melter and proceeding toward the nip;the ribbon of glass reaching the nip between the first and second rollers at a temperature of from about 1,900-2,400° F.;forming an antique pattern in at least one surface of the glass ribbon in the nip, by causing the antique glass pattern to be transferred from the at least one roller to the ribbon of glass;the patterned glass ribbon exiting the nip at a temperature of from about 1,100-1,600° F.;annealing the patterned glass ribbon after the ribbon has left the nip; andcutting the patterned glass ribbon into a plurality of sheets which simulate antique glass sheets from a visual perspective. 2. The method claim 1, wherein the antique pattern is provided on only one of the first and second rollers. 3. The method claim 1, wherein each of the first and second rollers are liquid cooled in a manner such that liquid within the first and second rollers is at a temperature substantially less than a temperature of the glass ribbon when the ribbon is in the nip between the first and second rollers. 4. The method of claim 1, wherein an average height of the ridges is from about 0.0001-0.030 inches. 5. The method of claim 1, wherein an average height of the ridges is from about 0.0005-0.005 inches. 6. The method of claim 1, wherein the ribbon of glass reaches the nip between the first and second rollers at a temperature of from about 2,000-2,300° F. 7. The method of claim 6, wherein the ribbon of glass reaches the nip between the first and second rollers at a temperature of from about 2,100-2,200° F. 8. A method of manufacturing antique patterned glass sheets, the method comprising:providing a furnace or melter;providing first and second opposing rollers which define a nip therebetween, and providing at least one of the first and second rollers with a pattern including a plurality of intersecting ridges of different lengths defined in an exterior surface thereof;a ribbon of glass exiting the furnace or melter and proceeding toward the nip;the ribbon of glass reaching the nip between the first and second rollers at a temperature of from about 1,900-2,400° F;forming a pattern in at least one surface of the glass ribbon at the nip, by causing the pattern to be transferred from the at least one roller to the ribbon of glass;the patterned glass ribbon exiting the nip at a temperature of from about 1,100-1,600° F.; andcutting the patterned glass ribbon into a plurality of antique patterned glass sheets. 9. A method of manufacturing antique patterned glass sheets, the method comprising:providing a furnace or melter;providing first and second opposing rollers which define a nip therebetween, and providing at least one of the first and second rollers with a pattern including a plurality of intersecting ridges of different lengths defined in an exterior surface thereof;a ribbon of glass exiting the furnace or melter and proceeding toward the nip, wherein the glass reaches the nip between the first and second rollers at a temperature of from about 2,100-2,200° F.;forming an antique pattern in at least one surface of the glass ribbon at the nip, by causing the pattern to be transferred from the at least one roller to the ribbon of glass;the antique patterned glass ribbon exiting the nip at a temperature of from about 1,100-1,600° F.; andcutting the antique patterned glass ribbon into a plurality of antique patterned glass sheets.
