Pot′ting-cask.

（Sugar.) A hogshead with holes in the bottom into which imperfectly crystallized sugar is dipped in order that the molasses may drain from it. In each hole is placed a crushed stalk of cane or plantain, which reaches to the top of the sugar. The molasses passes off through the spongy stalk, leaving the sugar comparatively dry and more perfectly crystallized.
