Excerpt from The ABC of Iron
There is nothing so essential for a foundryman to understand as the action which the different elements in pig iron have on his product. Manufacturers now realize that pig iron is not a simple substance, but is in reality an alloy compound of a number of elements very dissimilar; that its physical characteristics, strength, elasticity, etc., depend upon the percentages of these elements.
Greater knowledge is being sought concerning the chemical questions involved in foundry practice, and as this knowledge is resulting in the production of better and cheaper material, it becomes necessary for the foundryman who would successfully meet competition to study this well. No foundryman can afford to be ignorant of the nature and properties of iron if he expects to overcome the numerous emergencies that beset every melter of pig iron.
The increasing inquiries on these subjects suggested the publication of this book.
Learned discussions are had on these subjects before societies and mechanical institutions, and papers are written on special subjects which are reproduced in piece-meal in our trade papers and journals. Only few, however, have the opportunity or can afford to attend the meetings of these societies, and the majority do not get to see their transactions published.
There are very valuable works published on the metallurgy of iron and steel, but they are voluminous and technical, and for this reason very discouraging for a beginner.
