TO DYE BLUE.
Fill your crucible three parts full of soft water, and put it on a slow fire, at the same time put in your blue ingredients, previously prepared, (this is done by dissolving the powdered blue in oil of vitriol and water in a stopper bottle for twenty-four hours). If there is a very light shade of blue required, put in a couple of table-spoonfuls of the blue ingredient, and add to it as the shade may be varied at will according to the quantity of the stuff; boil the hackles in tartar and alum, say a table-spoonful of each, or rather less of the tartar, simmer it on the fire for two or three hours according to the process mentioned before; and when the proper colour is produced take out the hackles, hair, or fur, and wash them well in soap and hot water.
There is a paste blue prepared at the dry-salters all ready for the dye pot, take a table-spoonful of it and stir it well up in your pot nearly full of soft water, and boil it gently for about an hour (or less), then put in your hackles or hair, previously washed and wet going in, boil for two hours very slowly and wash off the dye; any shade of blue may be had in a very short time by this process; there are two or three dry-salters in Long Acre where this paste blue is sold, and any of the other ingredients may be purchased at their shops, or at chymists.
TO DYE RED.
Prepare your dye pot by nearly filling it with soft water; and keep it at a scalding heat when the dye stuff is put in, as it must not boil, if it is allowed to boil it becomes dull in colour; put into the dye pot a handful of finest grape madder, and simmer it slowly over the fire, stir well, and prepare the hackles or hair in the alum and red tartar liquor; after having boiled an hour slowly, take out a bunch and look at them between your eyes and the sun or light to see how they take the dye, if too pale there must be more madder added, and allow them to remain in the dye all night, simmer them slowly, next day take them out, rinse and wash them well, and allow them to dry in the air; mix a table-spoonful of cochineal with the madder.
TO DYE ORANGE.
When orange is desired take a handful of best madder and mix it with a spoonful of cochineal, boil it for an hour or two, add too a little ground red wood which requires more boiling than the madder itself; dye your hackles or stuff yellow first, and dip them into the red dye a short time, take them out and look at the shade you have; if too light allow them to remain in longer, and you will have darker shades of colour, put a little red tartar and ground alum into the dye to assist the red wood to strike on the materials, take them out and wash them in soap and hot water, and afterwards rinse them in urine which gives a lustre and softness to the stuff.
