A vat container is a large container used for storing or holding liquids, especially in industrial settings. Vats can be made of various materials, such as wood, metal, or plastic, and can be used for a variety of purposes, such as storing wine, holding liquids for manufacturing processes, or fermenting or ripening liquids. Vats can also be used for dyeing textiles, where the dye is steeped in the liquor and exposed to the air to convert it by oxidation to the original insoluble dye and precipitated in the fiber. Vats can be found in various sizes and shapes, depending on their intended use.
