As fustic and logwood are to form part of this dye upon the annatto ground, the silk must be alumed, then washed from the alum, in order that the superflux of the alum may not render the dye uneven. A fresh liquor is then prepared, rather hot, to which must be added a little of the decoction of logwood, and of the decoction of young fustic. The silk is returned in this liquor, but if apparently too red, you may put in a very little of solution of sulphate of iron, which will make it sufficiently yellow.

When the silk is dyed with the gum, in the raw state, the annatto must be used nearly cold, or the elasticity of the silk will be destroyed.
