Turmeric or Indian Saffron. A root brought from the East Indies, and employed in making a yellow dye. The colouring matter it yields is very abundant, and of great brilliancy of tint; but it possesses no durability, nor have any mordants yet been discovered sufficiently powerful to fix it. Common salt and ammonia have been recommended for this purpose; but they are found to deepen the colour, and incline it to brown.
