The making of Minium or Red Lead.

FIrst they take Lead and waste it in an Oven or Furnace: that is bring it to a Substance almost like a Litharge, by stirring it with an iron rake or how. This they grind with two pair of stones which deliver it from one to another: the first grind it courser, the the second finer [There is a mill so contrived as that it moves at once six pair of these stones] Thus reduced to powder and washed it is put into an Oven or reverberating Fur∣nace, and, by continual stirring with the iron rake or how, it is brought to the right colour in two or three dayes. The fire must not be extreme all this while, else it will clod toge∣ther and change colour. The iron rake wherewith it is stirred is hung or poised on an iron hook, else it is so heavy that it could not be moved by one man.
