a) Estimated change in the solution composition during crystallization from a solution with [Ca²⁺]=2.5 mm and [PSS]=250 μg mL⁻¹. b, c) Crystals grown from 1–3 μm calcite seed crystals in a continuous‐flow cell from a solution with a constant composition of [Ca²⁺]=3.2 mm, [HCO₃ ⁻]=6.4 mm, [NaCl]=35 mm, and [PSS]=250 μg mL⁻¹. Ionic strength=0.05 mm, pH 8.5, SI=1.4.
