(3) GREEN FOR WOOL

Mordant with alum and cream of tartar, add to the mordanting bath a little weld or fustic. Dye with 6 ozs. fustic (or weld). Dye in a separate bath with indigo extract, a rather bluer green than is wanted. Then put into a yellow bath till the right shade of green is got.

(4) GRASS GREEN

For 1 lb. wool: 1-1/2 oz. alum, 1/2 oz. sulphuric acid, 1/2 oz. salt, 1/4 oz. Tin crystals. Dissolve tin in separate saucepan and mix half of it with 1/4 oz. Flavin, add both to the bath together with indigo extract (1/2 tablespoonful). When hot enter yarn and boil hard for 1 to 1-1/2 hours. It turns a green when exposed to air. Wash very thoroughly.

(5) JADE GREEN (1 lb.)

Mordant with 1/3 oz. Cream of Tartar and 4 oz. Alum for 1/2 hour. Take out wool and air. Cool bath a little and add half the amount of the indigo extract to be used (according to shade of green required, 1/2 oz. indigo extract makes a good colour). Enter wool and stir rapidly for 5 minutes or so without boiling. Take out wool. Mix in the rest of the indigo extract. Enter wool and boil for 10 minutes. Take out wool. Throw away a quarter of the water and add some with 3/4 oz. fustic extract. Enter wool and boil for 1/2 hour to an hour.
