随机相互作用的p态波茨自旋可能冻结成波茨玻璃相，其中波茨对称性平均未破缺。提出了这种相变的平均场理论。与自旋玻璃的情况下，存在两个不同的Potts-glass阶段，不同的性质的相关性之间的许多简并基态的系统。对于p> 4，从无序相的转变是不寻常的：冻结不连续地发生，但没有潜热。类似的结果也适用于平均场四极玻璃模型。
Randomly interacting p-state Potts spins may freeze into a Potts-glass phase in which the Potts symmetry is unbroken, on the average. The mean-field theory of this phase transition is presented. Unlike the spin-glass case, there exist two distinct Potts-glass phases that differ in the nature of the correlations among the many degenerate ground states of the system. For p> 4, the transition from the disordered phase is unusual: The freezing occurs discontinuously but without latent heat. Similar results hold for mean-field quadrupolar-glass models.
