玻璃形成熔体中多价元素的氧化还原平衡可以用几个不同但相似的化学方程式表示。每个方程试图描述熔体温度，基础组合物，强加的氧逸度，多价元素浓度，和其他氧化还原组分的存在下诱导建立的氧化还原平衡的影响。氧化还原动力学，或在熔体中达到平衡的速率，证明了溶解的多价物质和气态氧化还原组分之间的相互关系。氧化还原气体（例如氧气）扩散到静态玻璃形成熔体中或从静态玻璃形成熔体中扩散出来控制熔体的氧化还原状态可以多快地改变。因此，平衡和动力学氧化还原过程对于所需玻璃/熔体性质的发展是不可或缺的。
Oxidation-reduction (redox) equilibria of multivalent elements in glass-forming melts can be expressed by several different, yet similar, chemical equations. Each equation attempts to describe the effects that melt temperature, base composition, imposed oxygen fugacity, multivalent element concentration, and the presence of other redox components induce on the established redox equilibrium. Redox kinetics, or the rate at which equilibrium is attained in the melt, demonstrates the interrelationship between the dissolved multivalent species and the gaseous redox components. The diffusion of redox gases, such as oxygen into or out of a static glass-forming melt controls how fast the redox state of the melt can change. Both equilibrium and kinetic redox processes are thus integral to the development of desired glass/melt properties.
