This image depicts all the processes of silk dyeing as taking place in a single room. The dyestuff is prepared, the skeins tied off to keep the yarns from tangling. The skeins are then mordanted and dyed. The cauldrons at right are suspended in the masonry support with the heat source beneath or surrounding the vat. Source: Teinturie de Riviere.
