Abstract: A fat skimmer for separating an unwanted fat liquid from a wanted liquid is provided which consists of a transparent cone shaped jug for storing the unwanted fat liquid and the wanted liquid that is to be separated. The jug has a tapered exhaust conduit formed at a central bottom end through which the wanted liquid will pass by force of gravity. A valve is within the conduit for selectively permitting passage of the wanted liquid through the conduit into a vessel which is positioned below the conduit, while the unwanted fat liquid is retained within the jug.
