This wood, the Moras tinctoria, is a native of the West Indies, and affords much colouring matter, which is very permanent. The yellow given by fustic without any mordant is dull and brownish, but stands well. The mordants employed with weld act upon fustic in a similar manner, and by their means the colours are rendered more bright and fixed. The difference between them is, that the yellow of fustic inclines more to orange than that of weld; and as it abounds more in colouring matter, a less quantity will suffice.
