Extended Data Fig. 9: Results of equivalence tests between sample IW (grains retrieved after IFCI runs inside water droplets, deposited at ceilings and walls) and natural ash grains (Nat1–Nat6).

Values represent the calculated minimum range D, under which the equivalence test would still be passed. The maximum value of D for each shape parameter is presented in the column labelled “max. diff.”. If this value is equal or smaller than the threshold for curvi-planar ash grains (Dmax, see also Extended Data Fig. 6), the compared datasets can be treated as significantly similar in the according shape parameter. Equivalence test results are only valid for datasets with homogeneous variances. If this precondition is not fulfilled, results were omitted, denoted by “(...)”. None of these values exceed the threshold given by Dmax, hence it can be concluded that IW particles and natural grains show no detectable difference in their shapes.
