Gaughing water: Excess water mixed with plaster ,makes manipulation quite easier . mechanism of setting in gypsum is explained through 3 theories out of which dissolution precipitation theory is widely accepted.                                    Advantage: 1)record fine details with least pressure 2)dimensional changes very minimal  3) economical Disadvantage: 1)gag reflex 2)cannot be used in undercut regions  Thanks for reading kindly comment down ur suggestion below
