The invention discloses a glass conveyor for a glass tempering furnace. The glass conveyor comprises a ceramic belt (1) consisting of ceramic sheets (11). The ceramic sheet is uniformly provided with through holes (13) passing through the upper and lower surfaces of the ceramic sheet and distributed along a longitudinal direction. A gap (12) is formed between each two adjacent ceramic sheets (1). The ceramic belt is driven by a driving roller (2) and is positioned by 3-15 driven rollers (21). The driving roller (2) and the driven roller (21) have the same diameters and the center lines are on the same plane. 3-15 blast air grids (3) are arranged in a ring formed by the ceramic belt (1). A blasting direction tilts to a glass transport direction. The glass conveyor realizes uniform heating of glass and small glass damage probability.
