"A curious and noteworthy instance of foundry work is reported. It consisted of three plates of cast iron about one-fourth of an inch, and seven by five inches in surface, covered with writing indented in the iron.
The impression on the iron is made by writing on thin paper, pinning the paper in a mold and then pouring on the iron.
The writing thus transferred to the plates when the iron is cooled is wonderfully clear and distinct, and is so deeply imprinted as to defy any attempt at erasure."

Writing cast in Iron
Fascinating and worth trying today.
