Paper mending and repair techniques and secrets. Episode two, repairing and mending clean Irregular Tear.

   The tears tend to be irregular when it is across the grain direction and tends to be "straight" along the grain direction. Remember! Mechanical made paper has a grain direction.
Why mechanical paper has grain direction? Because the fibers travel through the machine on a vibrating mesh, they tend to line up in the same forward direction, parallel to the direction of the side edges of the paper. It means that the handmade paper has no grain direction.

Straight paper tear

These tutorial episodes are for trained conservators who have the training and the experiences as well as the materials and tools to do this. However, if you are not a trained conservator and do not have the right materials for such repair and have some books with cuts and tears please don't use all types of commercial self-adhesive tapes these products should be avoided in historic document conservation and restoration. keep in mind the reversibility possibility of these products.

Also, you should keep away from
  • All types of scotch tape, sellotape, Etc. 
  • Filmoplast P Tape, it is an archival grade material, but not recommended for rare books due to its reversibility.
  • Heatset tissue (shiny and uses heat). However, it is reversible with...

Paper Mending

   New series of paper mending conservation and restoration tutorials which will focus on the techniques and secrets of paper conservation. keep tuned on, these tutorials will be captured regularly in short and informative episodes. Keep tuned 😉

just be careful during the repair process and Don't use:
  • Tape (sellotape), scotch tape, Etc.
  • Filmoplast P Tape, it is archival but not recommended for rare objects due to its reversibility.
  • Heatset tissue (shiny and uses heat). However, it is reversible with isopropyl alcohol, acid-free, and buffered with magnesium carbonate. As well it has long fibers, and it is transparent.

In conclusion, all types of commercial self-adhesive tapes should be avoided in historic document conservat...

What is Electroluminescent



The most common electroluminescent (EL) devices are composed of either powder (primarily used in lighting applications) or thin films for information displays (Wikipedia).

To put it simply, EL lamps or "high field electroluminescent" lamps use electric current directly through a phosphor to make light. Unlike most lamps, they can be shaped to be extremely flat, or in narrow wire-like shapes. Electroluminescence or "EL" is the non-thermal conversion of electrical energy into light energy. This phenomenon is used in EL lamps, LEDs, and OLEDs (edisontechcenter)

In the field of paper and book restoration and conservation 

EL is a sheet of thin and flexible plasti...
