Abstract: Methods for continuously manufacturing crystallized glass curved panels and pipes. The crystallized glass flat panel can be reformed by re-heating process. The method includes a reforming bed in the tunnel furnace that helps the flat panel to deform during transition. Three different reforming bed designs and processes are invented to produce convex and concave curved panels and pipes. In producing the pipe, both surfaces of the opening edges of the open pipe will be liquefied to liquid glass, even the pre-existing crystal structure. A roller squeezer will squeeze both edges together tightly, so they will be fusion bonded together. The closed pipe will be crystallized again so the crystals can grow between the bonding edges. The crystallized glass panel are made from crystallizable glass consist essentially of SiO2—Al2O3—CaO or SiO2—Al2O3—CaO—ZnO, or alike.
