Scope note:

Components of scouring machines, typically made of cast iron and equipped with a perforated bottom and sequeeze rollers, designed to wash shorn wool to remove unwanted contaminents. Specifically, these bowls are filled with a mixture of water, detergent, and sodium carbonate or another alkali acting as a detergent builder to achieve grease emulsification. Typical scouring machines incporate two to four bowls, on top of which wool is fed by sets of harrows as a saturated mat. As both water and the wool are fed into each bowl at the same time, in the same direction, the wool fibers are agitated and dirt or grease is freed from the surface of the wool. In conjunction with a heating component and a series of rinsing bowls, these bowls then utilize squeeze rollers to remove persistent grease from the wool materials.
