My mom claims that the shells themselves helped the grounds precipitate out. She tells me that when she was a girl (in the 40s) her folks would just put a pot of water on the burner with some coffee grounds thrown in. After a few minutes they'd throw eggshells in to get the grounds to settle and then pour themselves a cup. When the inevitable company would come by, they'd just add more water and more coffee, and throw more eggshells in.

More than likely the egg shells had remnants of egg albumen (the whites), left/stuck on them. Albumen was used/works (among other things) as a fining (clarifying) agent in wine making/beer brewing & also works here.

FWIW - I was told this is actually a small grain mill for making rough flour for hardtack, but this is just word-of-mouth.  I never researched it in depth.

Posted November 8, 2012 link

Hard tack is pre made in factories and not in the field. The grinder may have been used for other uses once you have one but the primary use and the reason it was there is for coffee.

The link above says that the conclusion that it wasn't used for coffee is based on it not being a very good coffee grinder.  That doesn't seem to stop the production or sales of whirly blade grinders...  ;)

John, I know just from my memory bank & going back to when I started out homebrewing & winemaking in 1971., & reading that in the days of old time brewing & wine making in books on the subject that I have.
Another olden time fining (clarifing) agent was Isinglass, which originally was the dried & pulverised swimm bladder of the Sturgeon if you can believe it. {;-)

Did anybody think that drinking dissolved crushed egg shells is not healthy? This is very dangerous.
