These require but twenty pounds of soap for boiling white. To dye aurora the silk must be prepared the same as for yellow.

Annatto prepared (as directed in the last article) and settled, is then put into a copper of hot water, in quantity according to the shade required; having mixed it well, the liquor being as hot as the hand will bear, put the silk into it; when one hank is tried, as in the yellow, if it be not full enough, the liquor must be strengthened till the colour is brought to the shade required. When finished the whole must be washed twice and beetled. The aurora serves as a ground for moidore.
