‎Scarce German edition of this collection of Glaubers main works in chemistry, alchymy etc. He was certainly one of the most remarkable chemists of the seventeenth century. ""Glaubers interest in the transmutation of metals and in industrial chemistry (e.g. his Glauber-salt) distinguished him from Paracelsus and other iatrochemists, who were more narrowly concerned with the preparation of chemical medicine. In the most general sense Glauber sought to perfect nature for the enchancement of human life - to render useless things useful through the release of their hidden virtues. Such changes were effected in his laboratory primarely through the ""ripening"" powers of salt...Glauber prepared his ""Most secret salt"" by combining ammonia and salpeter, made from excrements and urine"" (DSB). - Ferguson I:p. 328.‎
