Promoting Natural & Cultural History
A selection of 68 trade cards and bill-heads from 1703 to 1818 demonstrate some fascinating facts of the dyers and cleaners of London. To regard oneself as silk dyer dominated, whilst secondary titles were scarlet dyer, scourer or cleaner of various garments, dyer of cotton/calico or woollen fabrics. These randomly preserved trade cards and receipts also give some idea of preferred colours by the customers and all other services that were available in such establishments. Additionally, this case study will include some information about the most used and desired natural dyes – in a time when neither synthetic dyes or dry-cleaning with non-water based methods were invented.
A search for “trade card dyer” in British Museum’s collection online returned 68 results and all of these traders worked in London. Even if 50 establishments or ca 75% were named “Silk dyer” – these professionals were also often taking care of other materials like cotton, wool and linen garments or interior textiles. For example William Marsh who was a Silk-dyer at the Rainbow & Bush in Brook Street Holborn London stated in 1802: ‘Dyes all Sorts of Silks, Silks; Worsted and Cotton Furniture, Blankets and Quilts’. Additionally ‘Mens Cloaths Scower’d [scoured] Wet or Dry’. That is to say that cloths were scrubbed clean before the invention of non-water based cleaning processes in mid 19th century. The remaining 18 dyers described their occupations as follow:
Even if this selection of documents are too small to prove or explain fluctuations in the dyer’s trade in London, it gives a brief view of such businesses. Twenty-two of these cards are undated, but in general all trade cards and receipts originate from the 18th century and up to the 1820s. The dated examples may be divided into the following time periods, showing the quantity within each period:
A multitude of services were additionally listed on these card, whilst textiles of all materials could either be dyed, cleaned or both. For instance woven textiles as brocades, blankets, bombasins, calicoes, carpets, Genoa damask, mantuas, mohair fabric, paduasoys, satins, shagreens, tabbies, velvets and worsted camblets. But an array of other specialised work was also available for dyeing, thorough cleaning or other services, here are some examples:
A brief description of the complex process of natural textile dyes include that some sources of dye were readily available, especially for yellow and brown, since these colours could generally be prepared from plants that grew locally. The best yellow dyes came from weld or mignonette Reseda luteola, chamomile Anthemis tinctoria, saw-wort Serratula tinctoria, silver birch Betula alba, and heather Calluna vulgaris. To make brown various barks (oak often preferred), mosses and lichens were usually used.
Traditionally, blue had been obtained from woad Isatis tinctoria grown in England, but even before 1700 this generally had to compete with imported indigo (a number of varieties of indigofera). For a long time indigo was the dye imported in the greatest quantities, both by the British Empire and the other sea-going nations of Europe. The indigofera came from a wide range of places in America, the West Indies, India and Africa, with Bengal in India the place preferred by the British as the source for indigo at the end of the 18th and in the first half of the 19th centuries. This was a valuable source of dye that could be picked, dried, worked, compressed and packed in chests to be transported to Europe.
Orchella or archil, a source for popular red-lilac or blue-violet colours, was a lichen imported mainly from the Canary or Cape Verde Islands. But the best and most durable red dyes came from imported madder Rubia tinctoria which reached England mainly from Smyrna, Leghorn (Livorno) and Trieste. Two alternatives for red were Lac Dye, shipped from India, or strongly coloured carminic acid derived from the cochineal scale insect Coccus cacti. Lac Dye contains a deep red colouring agent. The scale insect cochineal originally came from South America via Spain, but was also freely cultivated in plantations in the Canary Islands – after the period (1830s) discussed in this case study – because of the dye’s huge popularity in Europe.
Greens could only be made by first dyeing yellow and then blue. Dyeing black or grey was the most difficult of all, since no plant naturally provides black or blackish dye. So the dye normally used for brown had to be supplemented with large quantities of iron vitriol and galls which often damaged the textile material, making it brittle. There were other methods that involved combining sufficient quantities of red and blue, whilst this was an expensive way of obtaining dark colours and so seldom used, but may have been used by professional dyers in London where customers were in the position to pay for such services. In general, the dyeing of cloth and yarn involved various degrees of costliness and hence varying status, with red, green and blue nearly always requiring an expensive outlay on imported dyes and frequently complicated dyeing methods as well.
A few other colour studies of the trade cards may finally be concluded with some notes of greens, reds and blacks – all costly colours to dye.
