Here, having killed common copper, it is revived again; that they call 'living copper.' / Then, one part of that copper and two parts of gold—thus melting the three parts, one should make that thick sheet. / Then, having killed lead with realgar and lemon juices, the thick sheet is to be smeared on both sides with that killed lead. / Then, having made a powder with equal parts of chalk and salt and filled a pot, having placed the sheet inside it immersed vertically, having put an inverted saucer over its mouth, smeared the neck below with clay, and placed an inverted lid over the saucer, a fierce fire is to be ignited beneath the pot for four watches. / And when this is done, three split layers of the sheet are produced. / Then, taking whichever is the middle split layer, it is to be ground, and the two flank split layers are to be discarded; and that which is the powder of the middle split layer is called the gold amalgam. / Its sixty-fourth part is to be given, according to the aforesaid method, to the previously mentioned mercury. / In this way, until it is eightfold, having given the gold amalgam, it is calcined-digested according to the aforesaid manner. / Thus the supreme gold amalgam is completed.
