About putty impression material
Putty is the thickest of them, and it shrinks the least on setting because it carries the most filler. It reproduces fine detail only down to about 75 microns, so it is not used on its own to take the impression; it supports a light body material, which is the putty-wash technique. It is supplied as two pastes of putty consistency in equal quantity, mixed by hand and placed in the tray.
The tray half of a putty-wash pair, kneaded by hand rather than pressed from a cartridge. Because it is hand-mixed, a review notes that polyethylene or vinyl gloves are named in place of latex for handling it.
