Preservation Services




Estoric employs paper preservation experts who specialize in the following conservation areas:  

Paper Tears: Traditional mending of tears in paper is standard practice in paper conservation, and should be done with the correct weight and tone of Oriental paper (Japanese paper called Washi, or Korean paper called Hanji).  These pieces of paper used to bridge tears should be torn to feather the transitional edges, and should be adhered with archival starch paste. Zin shofu a gluten free wheat starch paste is considered the best and is the only adhesive Estoric use for these repairs.

Leafcasting:  This is conservation technique of infilling losses with paper pulp on a small paper-making machine.  The conservation treatment involves careful dry-cleaning to remove surface dirt. The document is then washed in ethanol and deionized/recalcified water which removes soluble acids found in the paper and inks.   The losses and tears are then mended and filled with toned paper pulp using a small paper-making machine called a Leafcaster.   

Tape Removal:  Pressure sensitive tape comes in a wide variety of formulations, and has been used since the 19th Century as an expedient means to repair torn paper. ALL tapes cause serious problems including paper deterioration and staining.  Our experts employ a proprietary solution that has proven to be the best method to remove the offending tape and adhesive residue.  The chemicals used are highly toxic and must be handled with care,  but in most cases the staining can be successfully removed.

Stain Reduction: Paper stains typically occur from mold, acids, light or spillage influences.  Discoloration can be treated by various methods depending upon the source of the stain, the media, and overall condition of the paper.  Most stains can be minimized by careful washing, or by various conservation bleaching processes.

Vellum Conservation:  Very early books and documents spanning medieval times to the early 20th century were written or printed on vellum (parchment).  Vellum is made from the skin of an animal, usually calf, sheep or goat and is inherently very robust, lasting for centuries.  The parchment, however, is very susceptible to climatic changes, expanding and contracting with variations in humidity or moisture of any kind. This typically results in excessive distortions of the surface and from poor framing.  

Deacidification and Encapsulation:   
  • Deacidification  is a process of treating paper documents for the purpose of neutralizing acids within the paper and to create an alkaline buffer. High acidity levels contribute to the deterioration of paper, causing yellowing, brittleness, and instability. It is recommended that after deacidification single page documents be encapsulated in Archival Mylar. 
  • Encapsulation is the preservation process that provides greater support to a document that is in fragile condition.  It is a process that allows a fragile document to be sealed between two sheets of polyester film for protective viewing, ease of handling and framing.
