The fulling-stock may be made the vehicle for dyeing or staining all fancy colours, as drabs, beavers, slates, mouse, tan, rosy drabs, and many others. Some makers partially dye, and then complete the staining in the stocks.
(1) Take 1 1/4 lb. copperas, 1 pint pyrolignite of iron diluted with boiling water, 4 oz. Hofmann's auiline blue, 4 oz. indigo extract (free from vitriol, or this will turn it green), for 1 doz. hats.
Cream colour for 24 doz. 3-oz. bodies:
2 lb. red lead, 2 lb. common terra castle, 2 gills indigo extract in liquor, 3 gills orchil.
Mouse colour: 3 1/2 lb. common graphite (black-lead), 2 1/2 lb. best terra castle, 2 1/2 gills indigo extract in liquor, 4 gills orchil, 8 oz. red-lead.
An ordinary drab for soft hats: 3/4 lb. common graphite, 3/4 lb. best ditto, 3 gills orchil, 2 gills indigo extract; put the graphite into a pan, cover with water, and let down with sulphuric acid at 30° Tw.
Rose: 2 3/4 lb. common graphite, 2 gills indigo extract in liquor, 5 gills orchil.
Slate: 4 lb. common graphite, 4 gills indigo extract, 31/2 gills orchil.
Cinnamon: 3 1/2 lb. red-lead, 2 1/2 lb. best terra castle, 2 1/2 oz. picric acid, 1/2 gill indigo extract, 3 pints orchil. The picric acid is first dissolved in hot water, and the other ingredients are added.
To give the best results in fine fur hats, all the hoods should be shaved on a lathe before proofing. Many of the best makers assert that this class of goods will retain better colours by being mordanted before placing in the logwood bath. (Spons' Encyclopedia.)
