What the Wash Takes

Drum-Wash Time, Acid-Insoluble Ash and Water-Soluble Extractive in a Root Drug Lifted from a Sandy Bed and a Clay Bed

A paper from the School of Underlying Conditions washes 48 lots of one medicinal root crop, lifted from a sandy loam bed and a clay loam bed on one grower's property, for between 0 and 16 minutes in a rotary drum, and assays each for acid-insoluble ash and water-soluble extractive. Soil left the sandy-bed roots in a single fast phase and the clay-bed roots in two, the slow one lodged mostly in the crown, while extractive left both at about 1.2 per cent a minute; the wash line's rule of stopping when the water runs clear suited the first bed and overshot the second.
