Coagulation

1. (Science: haematology) The process of clot formation.

2. (Science: chemistry) The solidification of a sol into a gelatinous mass, an alteration of a disperse phase or of a dissolved solid which causes the separation of the system into a liquid phase and an insoluble mass called the clot or curd. Coagulation is usually irreversible.
