This is a great example of what a little makover can do for the usefulness of a vintage item.  My rusty jug/thermos is lined with 1/4" ceramic inside, has a thick glass stopper, and a metal cap to insulate its contents well.  It was used in the old days to transport hot and cold beverages in a large quantity.  With all the rust, it was no longer useable, so after sanding, wire brushing, and sealing—it is now in great shape to be used for liquids or as a fun accessory for your home.
