NOTES

1. The 20% ammonia solution can be replaced by 25% ammonia solution (d = 0.91), which is the solution usually supplied commercially.

2. Dissolve tannic acid (0.6 g) in water (100 ml), heat the solution to 60–70�C, and immerse cotton yarn (10 g) in the hot solution. Set aside the whole for 2 hours until it is cool, then remove the cotton, squeeze it free of liquid, immerse it in a cold solution of tarter emetic (prepared by dissolving 0.3 g antimony potassium tartrate in 100 ml water) for 20–30 minutes, and finally rinse it thoroughly with water. After the yarn has dried in air small portions of it can be used for dying tests.
