The effect on gelation is also illustrated by the change of viscosity of the sol with time.

This reagent is usually added to the sol, after evaporation and before gelation.

On the other hand, many gels cannot be reconverted into sols; that is, the "gelation" process is irreversible.

The kind of vessel in which gelation is induced varies widely in different factories.

Irreversible gelation is usually spoken of as "coagulation."
