Annotation	Beaking of the average cubic symmetry in Li-doped potassium tantalate was observed with quadrupole-perturbed 7Li NMR far above the nominal glass transition temperature. The observed spectrum consists of contribution from both isolated Li ions and from Li-Li pairs. It was found that the various Li-Li pair configurations are not equally probable. These are the first direct observation of biased ion ordering that persists at temperatures high above the glass phase.
