Existing comment: Paper & Ink:
Paper used for letter-writing and for newspapers was made primarily from rag waste. Wood pulp had been introduced but was not yet widely used. Rag paper is sturdy and long-lasting and does not deteriorate like modern newsprint does. The ink did not absorb into the paper but into the space between fibers.
The most common ink used was called iron-gall ink. The black pigment was tannin from insect nests on oak trees, and it was mixed from iron sulphate for acid content. Gum Arabic was used as a mixing agent to make it flow properly and water was added as needed. Ink was usually sold in sealed bottles but was also available in dry form in packets for travel. Because of its acid content, this ink damaged both pen and paper over time.
