Bubbling temperature direct affect the diameter and the distribution of bubbles; Bubblier is a main factor which influence the bubble structure of foam glass. To select different bubblier results in different craft. To add stabilizer directs affect the melt viscosity, besides superficial expansion.

在泡沫玻璃烧结过程中，发泡温度(760～950℃)影响泡径及气泡的分布状态；发泡剂是影响泡沫玻璃制品泡孔结构的主要因素，发泡剂不同，发泡时间不同，则气泡的泡径和开闭口的情况就不同；在泡沫玻璃烧结过程中，稳泡剂的加入直接影响粘度，粘度过高气泡不易产生，粘度过低气泡极易逸出，两者都不利于产生所要求数量的气泡；另外，表面张力和配料中的水对发泡也有一定的影响。
