In a Pickle Over Heinz Whatzit

[Anonymous]

This is a slightly-thicker-than-foil, half-dollar sized disc. I'd guess it was a bottle seal. Markings are: "H. J. Heinz Co." "Keystone Pickling & Preserving Works" "Patent May 1890"
The broken part probably read "Pittsburg[sic], U.S.A"
Can anyone tell me what anything about Keystone? History; How Old; What product this is from? What was the patent for? My searches have only produced the pickling crock with similar logo seen on linked page. My patent and trademark searches have been unsuccessful.
Thanks, Dan

Was trying to search patent by class and subclass(seals, pickling processes, etc.)without success. Was trying to avoid using patent numbers, but looks like that's where I'm headed. Steve, thanks for narrowing it down for me. Rhoderman-I was thinking ketchup or pickles-perhaps you're right, it could be horseradish as well. Thanks for the link. HH Dan

I think that you could still try using the class/subclass for a bit until you
