Section III.—Dyes and Colours.
The arts of dyeing and printing in colours have under-gone very considerable modifications during the last half-century, and perhaps no manufacturing processes havereceived more important assistance from the labours ofchemists. Dyeing is purelj a chemical operation; andconsequently it has improved in exact proportion to the
advance made in the investigation of those chemical lawswhich regulate the formation of colour, and the union ofcolouring matter with the various vegetable and animalsubstances which come under the operation of the dyer.A vast number of new colouring materials have beendiscovered or made available, and improved modes havebeen devised of economically applying those already inuse; so that the dyer of the present time employs manysubstances of the very existence of which his practicalpredecessors were wholly ignorant. From the increaseduse of many of the vegetable colours, and from the im-proved modes of applying the colouring matters, a demandhas naturally sprung up for various dye-stuffs; and at thepresent time, many of the dyeing materials of distantcountries are beginning to excite the attention of practicalmen; for though they have long been acquainted withmany of these substances, it is only recently that theprogress of the art has rendered their use desirable, oreven practicable.
At the present time, by far the greater number of thevegetable dye-stuffs used in Great Britain are derivedfrom foreign countries. The following Table shows thequantity of some of the chief of those substances importedin the years 1848, 1849. and 1850; but it must be re-marked, that it includes the quantities imported forre-exportation, as well as those retained for home con-sumption by our manufacturers:—
