Team working towards final steps of an intense task of books’ conservation

Team Heritage Preservation Atelier had a challenging task of conservation of a set of books that could not be digitized by a library because of the extremely brittle pages and stuck up and deteriorated condition. We started with making a detailed condition assessment report. After initial documentation, we opened up the worn out and damaged…

Studying Paper for presence of watermark and bluish tinge: Case of 150 years old drawing

The drawing under study is made in 1868 (as evident from the signature) and the watermark mentions the paper manufacturing year to be 1866. ‘Watermarks’ are markings put into paper during its production, by making thinner or thicker  layer of pulp when it is still wet. It becomes visible when paper seen with light source…

Case of a 150 year old engineering drawing

June 26, 2018   By Manit When we first saw the drawing on site, it appeared to be in a fairly good condition. Once it arrived in our conservation lab and we started a thorough diagnosis, there were a lot many observations and analytical details that were required to be considered before any treatment methodology…

one little observation while studying old miniature paintings

At times we find old sticky tape which leaves almost no adhesive on paper and does not make the paper brittle; instead, it makes its own plastic base brittle. Is this because of the adhesive chemistry itself or because of the pigment on the paper it is applied on?

Paper paintings and mounting issues

  We have learned while specializing in the field of conservation of cultural property (more specifically art, in the present discussion), about the specific type of material that should be used while mounting a painting on paper. The technique also matters a lot. One common technique of mounting involves creating ‘hinges’ on the mount board…

Issues in old books and traditional re-binding

When the pages have turned very brittle and there are tears, lost areas and old repairs with incompatible and damaging materials, it is not that simple to mend and rebind a book with traditional sewing technique.   Some binding procedures that cannot be performed properly or at all are:  We cannot trim the edges. We…

Sellotape: How it deteriorates and changes with time

What is sellotape?  Sellotape is basically a brand of transparent, polypropylene-based, pressure-sensitive tape. But, this term is also used for any such pressure sensitive tape of any brand. Sellotape is generally used for joining, sealing, attaching and mending. The older version of sellotape has shown some changes in its physical and chemical properties over a…

Paper and book conservation – Part 8

Once the old damaged binding was opened and stuck up pages of the books (to be treated) were separated/opened-up and the torn pages mended, the information in the books was digitally preserved. This digitization process was done before re-binding because it would have been difficult and damaging to digitize them in bound state. It is…
