Many a times while treating certain artifacts, specially on paper, one might feel that certain old repairs or treatments might be kept as such. But, when we proceed with the treatment we find that it was better if everything added as a repair was removed before starting our own treatment. Removing old repairs or not is an important point to be studied thoroughly while decision … Continue reading Conservation Lab: removing old repairs
Another opportunity for budding conservators to understand and learn: Conservation scenario in India The basic material and techniques used in archival conservation The basic materials and techniques in oil painting (on canvas) conservation possible job and business prospects Queries can be send here: Some glimpses from earlier workshops: Continue reading Getting ready for next workshop: March 2019!
Its our experience that insects that damage books are mainly attacking spine. This is because the spine receives liberal amount of adhesive while book making. After eradicating all the various stages of insects thriving in the books, book conservators repair damaged and deteriorated bound materials. We treat them further so that readers/researchers can consult them without further damage. Artistic features of a book, such as … Continue reading Bookworms love spines of books and hate anoxic environment

Aspergillus niger is one of the most active cellulolytic fungi. The roll of drawings in the above picture is mainly infested by A. niger and Chaetomium sp. as identified from the cultures isolated from the deteriorating inner-side of the roll. This culture was maintained on potato dextrose agar slants. Following are the digital pictures of the portions of the slides that were studied under a … Continue reading Aspergillus niger and Paper
This black powdery sheet (!) is not burnt paper, but, paper eaten by fungus. Cellulolytic microorganisms are hiding nicely all around us and are much more destructively powerful than we can expect from the tiny spores. Storage enclosures that were designed and created for protection turned out to be actually working with the deteriogens (deteriorating micro-organisms), by providing them not just the ideal and … Continue reading Paper burnt or eaten?
In paper conservation literature, there are many ways and materials advised to be used to remove foxing or at least lighten its scars. Here i am not going to suggest what to use, but would like to mention the importance of a thorough knowledge of chemistry and physics too apart from the deep appreciation of the art work and its technique! The conservator must know … Continue reading Removing Foxing is doable, but needs thorough understanding and patience too…
That peculiar smell/odor when some old books are opened, might at times be associated with mold and foxing. We come across books with foxing that may have very strong odor. All old books have vellichor, but some have stronger musty odor. Foxing is an age-related process of deterioration that causes spots and browning on old paper documents and books. The name may derive from the … Continue reading Foxing
We come across many different kind of problems associated with old black and white photographs. Fading, yellowing, redox blemishing, silver mirroring etc are some common problems with old photographs. These problems are generally due to the inherent causes or reasons present within the Photograph either because of the technique or material involved in making of the photograph. There are many additional problems that arise due … Continue reading Glassine stuck to a Photograph
All the conservation labs/workshops have mylar or melinex as the most commonly used material while treatment procedures as well as in packaging and safe storage or display etc. Such widely and frequently used material is known to all by these trade names (Mylar and Melinex), but not many know the exact properties and actual name of this material. The actual name is Biaxially-oriented polyethylene terephthalate … Continue reading BoPET: Mylar/Melinex/Hostaphan
Info from the print Condition Assessment We received the map in a folded form. There was some adhesive residue visible on the outside. On opening of the very first fold we found that due to the application of some adhesive, the folds were stuck to each other. There was an attempt in past, by someone to open it up despite the stuck-up condition. So, the … Continue reading Case study of conservation of a map
Finally, all the books that came to our lab have been restored and given a kind of new life. They are going back to the library tomorrow morning. Following is a re-sharing of a summary of all the conservation processes performed in our lab: Team Heritage Preservation Atelier had a challenging task of conservation of a set of books that could not be digitized by … Continue reading Paper and book conservation – Part 9
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 binding and treated each and every folio individually. Damaged signatures … Continue reading Team working towards final steps of an intense task of books’ conservation
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 at the back of the paper. This drawing was created … Continue reading Studying Paper for presence of watermark and bluish tinge: Case of 150 years old 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 could be prescribed or finalized. In this blog post we … Continue reading Case of a 150 year old engineering drawing

One of the miniature paintings we came across last month was showing some signs of biological degradation, but no active microbes were visible on the surface. This was unlike other miniature paintings of the same lot, which had visible mold on surface, specially at the back of the painting. This painting had no mold visible even at the back. But, at a closer look and … Continue reading Some deteriogens are very nicely hidden
When a conservator gets art works like the above miniature painting, it is not just the damages that interest him/her, it is also the history/mythology and story depicted in the painting that attracts the conservator. Story/history/mythology apart from the technique and place in timeline/age, would scale the importance of the painting. We study a painting for following aspects before going for actual conservation: Story/interpretation /mythological importance/historical … Continue reading Brief record of miniature painting’s assessment and conservation
Indian miniature paintings have various schools and technical differences, but most of them have thick paint layer and impasto effects. Thick paint layers tend to flake off under certain circumstances. This flaking can be very unstable/powdering off or more stable in the sense that flaking is not falling off easily… We at heritage preservation Atelier are consistently testing the efficiency of different treatment procedures adopted … Continue reading Flaking in Miniature Paintings
At the edge of a jungle, we found some ruins of a temple which was still functional in adjoining more recently constructed room. Initially when i visited the site in 2008, there was another structure right in the middle of the temple complex. This structure was now (2015) totally erased from the landscape. Only a defining foundation of it was left. This central part would … Continue reading Rescuing Frescoes from ruins
(June 2017 These days we are working on a few blue-prints and blue-lines in our lab. Before starting any work, we tried to discuss the original material and technique used into making them, with our team.) Both these processes use different light sensitive chemicals for re-producing or copying the original drawings made on translucent paper. These processes were discontinued over a period of time because … Continue reading Blue-prints and White-prints or blue-lines
Very often we have seen that old worn out paintings are pasted on thicker backing board or sheet. This initially looks good as the worn out or crushed paper or fabric looks much better as it acquires the smoothness and strength of the new backing; but, we tend to ignore that this is not for ever. Whenever the adhesive chemistry weakens with ageing and time, … Continue reading Painting, backing, conservation and Physics
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? Continue reading one little observation while studying old miniature paintings
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 at the back. We come across paintings that have been … Continue reading Paper paintings and mounting issues
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 can not round the spine. Using needle on a brittle … Continue reading Issues in old books and traditional re-binding

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 longer period of time due to ageing. Initially such tapes … Continue reading Sellotape: How it deteriorates and changes with time
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 always easier to digitize in a flat state.

Among the books being treated in our lab, one is binding of 12 journals from november 1907 to October 1908. Individual pages were mended with skill and patience. They were then joined at the central edge and signatures or journals gathered for final binding.. Continue reading Paper and book conservation : Part 5
Museum objects have so much to say! But their voice is outside their own existence.. Only curators can tell what the objects want to say, to the world, and that message should be correct! Moreover, if an object is being infested with some deteriogen, only curators can voice their pain to the doctors of the cultural objects,viz, conservators. This fact makes us understand the huge … Continue reading Curators are the voice of museum objects
Two major problems associated with old paper manufactured during mid nineteenth century onward are: Brittleness Yellowing or darkening Breaking of paper due to brittleness (loss of flexibility to bend without breaking) generally occurs in very old paper which was manufactured from wood pulp technology. Other feature found in such old paper getting brittle, is yellowing or browning. Paper becomes acidic either by absorbing pollutants such … Continue reading Paper and book conservation – Part 2
To understand and master paper conservation, one must understand the composition and manufacturing of paper. The composition of paper and raw material in its making has varied since its invention in 105 AD in China. The timeline of paper manufacturing technique and composition as understood from various sources is as follows: The invention of paper by T’sai Lun, a member of Imperial Guard and Privy … Continue reading Paper and book conservation- Part 1
Museums are the priceless treasures of our nation. It is our duty and responsibility to take good care of the the tangible culture housed in museums. This cannot be done effectively if we do not have our museums’ CMP (Collections’ Management Policy) and MAP (Museum Assessment Program) in place. First thing is to understand that museums can contribute in economy. They generate employment and can … Continue reading We need CMP and MAP in place for our museums
The kind of involvement it takes to create an art work at the level of mind and senses, makes the activity a form of meditation. The focus and spontaneity required not only keeps the mind free of negative thought process, but at the same time creates positive vibes of satisfaction, accomplishment and self worth. If the person involved in this form of skill has the … Continue reading Art and Culture as Rescue and Business
Museums are the reflection of any culture or city or a part of art/history. Tourists rarely miss a chance to visit any city’s museum(s) in their travel plans. But, museums are not taken seriously by their own caretaker government departments because they don’t seem to generate revenue. This viewpoint needs to be changed because they are actually always on the tourists’ interest and with proper … Continue reading Government Museums need more Government Care..
There are many methods used to secure the falling of pieces right in the beginning , before we start with other treatment procedures of conservation. These methods are extremely helpful as they allow the conservators work with more confidence while removing the surface accumulations that are damaging as well as obscuring the art work and other relevant details. allow safe movement of the artifact while … Continue reading Securing the flaking-off pieces
