Gwilt translation

10I have now to speak of those bodies which, from particular treatment, change their qualities, and acquire the properties of colours; and first, of black, which is much employed in different works, in order that it may be known how it is prepared for use.

Morgan translation

10I shall now pass to those substances which by artificial treatment are made to change their composition, and to take on the properties of colours; and first I shall treat of black, the use of which is indispensable in many works, in order that the fixed technical methods for the preparation of that compound may be known.
