Sop

The historian W.L.J de Nie translates ‘sop’ as ‘dye bath’, but ‘solution’ is more appropriate. The same word can be found in ‘zeepsop’ (‘soap solution’) which is still in use in modern Dutch. (De Nie, De ontwikkeling der Noord-Nederlandsche textielververij, Appendix (Bijlage, Lijst II), XXII.)
