Abstract	Innature, nonequilibrium systems reflect environmental changes,and these changes are often “recorded” in their solidbody as they develop. Periodic precipitation patterns, aka Liesegangpatterns (LPs), are visual sums of complex events in nonequilibriumreaction–diffusion processes. Here we aim to achieve an artificialsystem that “records” the temperature changes in theenvironment with the concurrent LP formation. We first illustratethe differences in 1-D LPs developing at different temperatures interms of band spacings, which can demonstrate the time, ramp steepness,and extent of a temperature change. These results are discussed andaugmented by a mathematical model. Using scanning electron microscopy,we show that the average size of the CuCrO4 precipitatealso reflects the temperature changes. Finally, we show that thesechanges can also be “recorded” in the 2-D and 3-D LPs,which can have applications in long-term temperature tracking andcomplex soft material design.
