In February, TSLAC Conservation observed a significant milestone: the completion of our long-running treatment project on our oversize Confederate Muster Rolls.
TSLAC’s Confederate Muster Roll collection documents vital information about Texans who enlisted to serve in the Civil War. These documents hold great research interest for historians and genealogists. They state the soldiers’ name, age, rank, and place of origin; sometimes they list items the soldiers brought into service, like guns and horses; and sometimes they include payroll information.
At some time in the early-to-mid 20th century, these documents underwent a popular treatment called “silking.” A thin piece of silk was adhered to both sides of each sheet to hold brittle, fragile pieces together. Unfortunately, we now know that silk is acidic, and acid causes paper to turn even more brittle and brown than it might have originally.
Starting in 2010, we have taken approximately 15 muster roll sheets per month into the lab to remove the silking and deacidify the paper. We also stabilize iron gall ink with a calcium phytate treatment. Tears are mended and the sheets are sleeved for storage and handling. This treatment prepares the documents for scanning and enables in-person access in the reading room, which was previously restricted due to the documents’ fragile condition.
As we move on to work on other materials, we commemorate the close of this major project!
