When silicate solution is injected into a less dense metal sulfate solution, a reaction occurs, forming a macroscopic precipitation structure growing downward, the reverse of the "chemical garden" phenomenon. We introduce a novel analysis of this reaction—wavelet analysis of time-sequence images of the precipitation structure to characterize morphology as the structure grows. This wavelet analysis is used to analyze changes in the “reverse" chemical garden reaction under differing silicate concentrations.
