This item is a 19th-century stoneware jar, likely produced by Richard Remmey of Philadelphia, Pennsylvania, (i see.No signature, so this is just an assumption) featuring cobalt blue brushed floral decorations.

Material: Salt-glazed stoneware with a slip-glazed interior.

Design: Typically features a tooled shoulder and a squared rim.

Decoration: Hand-brushed cobalt blue foliate or floral motifs, commonly dangling tulips.

Origin: Often associated with the Philadelphia or Mid-Atlantic region pottery traditions.

Probably used to store food, jams, jellies or preserve item.

There is a little chip on the top rim.You can see it in the.

There is a  number

two stamped into the top m, representing two gallon.

I tried to take a photo of the inside.There is a buildup of glaze on the bottom on one section.

Please let me know if you have any questions at all.And I am happy to help.
