Question:

Hi.  Looking for assistance to determine what this is considered and what approximate value is.  Bottom is stamped Minnesota Stoneware Co. Red Wing. 

Pictures are attached. 

Answer:

Your Minnesota Stoneware Company Albany slip jar is called a wax sealer.  A wax sealer is an early canning jar.  When the jar was filled with its contents, a small tin cover was placed on top of the opening and hot wax poured over it to seal the opening.  These wax sealers wend out of production when the glass canning jars were invented.  In perfect condition, the value is $50 to $75.  Al Kohlman
