To Dye Purple Or Violet
First dye the hackles or stuffs blue, and lay them to dry; then, fill
the dye-pot more than half with soft water, and in the other pot prepare
the tartar and alum, dip your hackles into this for a little while, and
lay them on the table till you prepare the red dye; bruise a couple of
table-spoonfuls of cochineal, and put them into the pot of hot soft
water, boil for an hour, and put in the blue hackles, and allow them to
simmer over the fire very slowly to keep them from burning; when you
have the proper shade, take them out and wash them well.
