Microcrystallized glassware suitable for open fire heating

The invention relates to microcrystallized glassware suitable for open fire heating. First, molded glassware is respectively subjected to chemical tempering and physical tempering. In the chemical tempering process, soaking is carried out with a high-temperature salt solution of cesium and potassium, such that chemical tempering of glass is realized. Sharp air-cooling molding is then carried out with a tempering furnace. According to the invention, the heating time for glassware with different thicknesses is precisely controlled. During the physical air-cooling process, the positions of upper and lower air grids, the wind speed and the air pressure are adjusted, such that tempering cold air is uniform. Arc tracked air-cooling is carried out upon edges of the glassware, such that the compressive stress of the glassware can reach 190-210MPa. 本发明种可明火加热的微晶化玻璃器皿，首先对成形的玻璃器皿分别采用化学钢化和物理钢化；化学钢化过程是用铯和钾的高温盐溶液浸泡，实现玻璃的化学钢化；然后用钢化炉进行急剧风冷成型。本发明通过对不同厚度玻璃器皿的加热时间的精确控制，以及物理风冷过程中的上下风栅位置和风速、风压的调整，使钢化冷风匀致，并对玻璃器皿边缘部进行弧度状跟踪风冷，使玻璃器皿压应
