Looks like a kim-chi crock ... or other oriental picked vegetable crock.

It definitely looks very similar you are right. Mine looks more basic on the rim. Do you have any idea of the age range?

The design has not changed in centuries ... it could be new or ancient.

Here's my tiny collection of Redware. It's made from clay which becomes red when fired, like a red brick or flower pot. What color is your crock on the bottom? Is your crock deformed on the side (maybe happened while firing?)
Early American stoneware is measured in gallons. Foreign stoneware will be measured in liters.

You might see metric markings on newer European crockery, but imagine if you have crocks with any age on them at all, they won't be. England is still sorting out the metric/imperial measures and often display in both on signage still today. So for old items, I'm not so sure you can make that statement.

there are no markings on it that i can percieve as being a number either liters or gallons. It looks to be around a 2 gallon i would guess.

I understand that there are no markings on the crock, there are no markings on any of my redware, I'm not talking about markings. If you measure out 3 gallons of water and it perfectly fills up your crock then you have a 3 gallon crock. If it is an Asian crock it will have a different volume.
Could I ask erlybrd to tell us is the bottom unglazed? If so, what color is it?

yes it's red much like a brick or flower pot.

Look at the shape of the redware and the shape of the crock in question ... they are not similar. Red clay body pottery can be found all over the world - it's not all "redware" from America.

A kim-chi crock can be anywhere from tiny for a special batch to big enough to pickle an entire cabbage field's harvest. It might accidentally be a measure we use, or it might not.

Unless you can find documented American redware of that shape, with the matching cover, it's best to call it what it most resembles: an Oriental pickling crock of unknown age.

It very well may be what lazy is saying. I may even be looking at it totally wrong. Notice my lid. It's unfinished on top. However it is finished on the other side. If i put the lid down first like a plate under a flowerpot the entire piece is finished appearence wise. Maybe what i thought was the lid isnt even the lid. Is that possible?

This picture was taken in the courtyard of a restaurant when I was in Korea.

Their current stock of kimchee is in the pots, and the upside down one has been emptied and washed. (the supplier will take away the empties and drop off the replacements ... it's like an old-style dairy route, but with pickled cabbage)

Notice the strong similarity of the pots to yours, and the saucer-like lids with a rough unglazed side facing upward. The side facing the veggies, and the inside of the crock, is glazed to make cleaning the crocks easier.
