Gwilt translation

12It will be proper to explain in what manner white lead is made, and also verdigrease, which we call æruca. The Rhodians place, in the bottoms of large vessels, a layer of twigs, over which they pour vinegar, and on the twigs they lay masses of lead. The vessels are covered, to prevent evaporation; and when, after a certain time, they are opened, the masses are found changed into white lead. In the same way they make verdigrease, which is called æruca, by means of plates of copper.

Morgan translation

12It is now in place to describe the preparation of white lead and of verdigris, which with us is called “aeruca.” In Rhodes they put shavings in jars, pour vinegar over them, and lay pieces of lead on the shavings; then they cover the jars with lids to prevent evaporation. After a definite time they open them, and find that the pieces of lead have become white lead. In the same way they put in plates of copper and make verdigris, which is called “aeruca.”
