Tallow

It consists chiefly of a variable mixture of sodium salts of fatty acids, such as oleic and palmitic.

[10] According to a 1985 article in The New York Times, tallow was also used for frying at Burger King, Wendy's, Hardee's, Arby's, Dairy Queen, Popeyes, and Bob's Big Boy.

[12] Greaves (also graves) or cracklings is the fibrous matter remaining from rendering,[1] typically pressed into cakes and used for animal feed, especially for dogs and hogs, or as fish bait.

[15] Tallow also has a use in printmaking, where it is combined with bitumen and applied to metal print plates to resist acid etching.

Notes issued in 24 countries including Canada, Australia, and the United Kingdom were found to be affected, leading to objections from vegans and members of some religious communities.

[16][17] Tallow once was widely used to make molded candles before more convenient wax varieties became available and for some time after they continued to be a cheaper alternative.

[19] Early in the development of steam-driven piston engines, the hot vapors and liquids washed away most lubricants very quickly.

There is a trend toward replacing tallow-based lubrication with synthetic oils in rolling applications for surface cleanliness reasons.

[20] Another industrial use is as a lubricant for certain types of light engineering work, such as cutting threads on electrical conduit.

A combination of mutton tallow, paraffin wax and beeswax is still used as a patch or projectile lubricant in present-day black powder arms.
