To dye wool a grey.

All greys, from the darkest to the lightest, are composed of black in varying proportions. They are of great use in dyeing, not only for their own colours, but also when applied to other colours, which operation is called saddening or darkening.

Some greys have a woad ground of blue, then of log-wood, sumach or sulphate of iron, of which decoctions of the three last, for expedition, should be in readiness when wanted. When a succession of light shades, in particular, is required, in some instances the chemic blue is used: when we treat of the mixture of black, or rather grey with red and blue, the utility of grey will be seen.


Mixture of black or grey with red and blue.

These produce an mfinite number of all shades of grey as sage grey, slate and lead colour, and others still darker.
