The paste should be soaked in about its own weight of solvent, ideally for one to eight hours. Strong solvents, i.e. those that are highly polar, are best avoided as they can reduce the leafing effect. If using solvent alone is not feasible, the liquid coating medium can be substituted, but the dispersion time may be extended. Dispersion is best achieved by low energy stirring, using a slow speed blade capable of moving the whole mass. Further solvent or medium may be added at this stage. When a smooth consistency, free of soft aggregates has been obtained, the balance of the formulation may be slowly added. High shear should be avoided as it bends and breaks the flakes, reducing their brightness and leafing effect.
