Subject: Chipping burr grinder
 

Today, I was disassembling an antique manual grinder and found that some of the shiny metal coating on the conical burr's grinding surface is chipped off.  Does this make it unusable for food safety reasons?  Is there any way to remedy the wear?

Thanks for your help.

I'm not sure what coating you are referring to, it may be zink, a lot of food equipment is coated in zink. It will not harm you if you eat some of it.
It may NOT be zink too, "antique" is kind of a flexible word also,  I tend to think of 5 or more decades old to fit in that definition but even then it would only go back to the 60s and since I clearly remember the 60s (I was not old enough to do anything to NOT remember the 60s but don't ask about the 70s LOL) even then I don't think of that era as antique.

It may be most anything in there depending on where the grinder was made. Is there a pressing need to use that grinder? Perhaps it is time to put it up on the wall and just look at it?
