in metallurgy, a round pit of stone, lined with clay within, for the receiving the metal on its first fusion from the ore.

in the British salt-works, where sea-water is boiled into salt, is the name of a fort or pond, which is made at some distance from the saltern on the sea-shore, between full sea and low water mark. From this pond a pipe is laid, through which, when the tea is in, the water runs into a well adjoining to the saltern; and from this well it is pumped into troughs, through which it is carried to the cisterns, in order to be ready to supply the pans. See Salt.
