Red Wing Lye Crock


I purchased a stoneware container that is 6 in. in diameter and 12 in. tall. It has a lid
with Redwing stamped on it. The bottom has 2 holes fitted with washers and  connecters for something to screw into. No one has been able to tell me what this is, can you help me?

Thank you,


This is a Lye crock. It was used in dairy barns to clean milk equpiment.
