A short dictionary entry on the dye-vat, a beck or tub in which cloth or other goods are saturated with dye or mordant solution. It describes a roller-type vat in which a sewn-together piece of cloth circulates continuously through the liquid and is then wrung out. It also describes a dipping-vat in which goods in a basket are lowered and raised by crank and rope. Two engraved figures (1810 and 1811) illustrate the machines.
