Effective crystallization (growth) and dissolution times (t3) of unconfined NaCl crystal/droplet, determined by (GenRH/MCell; Hirox) at different RH targets between (20 and 90%). For the dissolution experiments t3 = t1 = t2 = t4 = t5, while for the crystallization experiments t1 and t2 can be derived from the data in the image and table to the right, with t1 = t4 − t5 and t2 = t4 − t3. Times t4 and t5 represented in red illustrate the times when crystallization takes longer compared to dissolution
