Satzblei is the German word for that alloy which in printing is used for characters. Often, it consists of lead, antimony, and tin: Lead provides for softness and ductility, antinomy caters for the necessary hardness, and tin is responsible for toughness and a good fusion of the metals.
My articles may be produced without that alloy these days, but not without its characteristics: I align my work with the requirements of the publications and their readers, deliver verifiable facts, and investigate pertinaciously, using numerous sources and contacts.
