The ribbon leaves the rollers at about 850°C and is supported over a series of water cooled steel rollers to the annealing lehr. After annealing the glass is cut to size. Wired glass is made in a double pass process. The process uses two independently driven pairs of water cooled forming rollers each fed with a separate flow of molten glass from a common melting furnace. The first pair of rollers produces a continuous
