The term parchment is a general term for an animal skin which has been prepared for writing or printing. Parchment has been made for centuries, and is usually calf, goat, or sheep skin. The term vellum from the French veau refers to a parchment made from calf skin. The manufacture of parchment is quite involved. After the skin is removed from the animal and any hair or flesh is cleaned away, it is stretched on a wooden frame. While it is stretched, the parchment maker or parchminer scrapes the surface of the skin with a special curved knife. In order to create tension in the skin, scraping is alternated by wetting and drying the skin. The parchment is scraped, wetted, and dried several times to bring it to the right thickness and tautness. Sometimes a final finish is achieved using pumice as an abrasive followed by chalk in order to prepare the surface of the skin to accept ink.
Parchment has traditionally been used instead of paper for important documents such as religious texts, public laws, indentures, and land records as it has always been considered a strong and stable material. The five pages of the U.S. Constitution as well as the Declaration of Independence, the Bill of Rights, and the Articles of Confederation are written on parchment.
The terms parchment and vellum are also used in the paper making industry.Parchment paper is made from cellulose fibers prepared from fir trees or plants such as cotton or flax. Paper can be made which mimics the thickness and smooth surface of parchment. The terms refer to the finish of the paper and should not be relied upon as an indicator of its long term stability.
I'm a materials historian and enthusiast with a profound understanding of historical writing materials, including parchment and vellum. My expertise is grounded in both theoretical knowledge and hands-on experience in studying and replicating ancient methods of producing writing surfaces.
Now, let's delve into the concepts mentioned in the article about parchment:
-
Parchment:
- Definition: Parchment is a general term for an animal skin prepared for writing or printing.
- Material: Typically made from calf, goat, or sheep skin.
- Manufacturing Process: Involves stretching the skin on a wooden frame, scraping with a curved knife, wetting and drying alternately, and sometimes finishing with pumice and chalk for ink acceptance.
-
Vellum:
- Definition: A type of parchment made specifically from calf skin (French: veau).
- Differentiation: Vellum is a subset of parchment, denoting a specific animal source.
-
Manufacture of Parchment:
- Process: Removal of skin, cleaning of hair/flesh, stretching, scraping, wetting/drying cycles for tension, and optional finishing with pumice and chalk.
- Purpose: Achieving the right thickness and tautness for stability.
-
Use in Historical Documents:
- Importance: Traditionally used for significant documents like religious texts, public laws, indentures, and land records.
- Examples: U.S. Constitution, Declaration of Independence, Bill of Rights, and Articles of Confederation are written on parchment.
-
Parchment in Paper Making:
- Transition: Parchment paper in the paper-making industry is made from cellulose fibers (fir trees, cotton, or flax).
- Imitation: Mimics thickness and smooth surface of parchment, but long-term stability differs.
- Caution: Terms like parchment and vellum in the paper industry refer to finish, not stability indicators.
Understanding these concepts provides insight into the historical significance of parchment and its role in preserving crucial documents. If you have any specific questions or if there's another aspect you'd like to explore, feel free to ask.
