Frescoes vs Tempera
When we talk about wall paintings or mural paintings, most of us call them ‘frescoes’. This might not be technically correct for all the murals.Technically, if the painting is created ( or we can say that the colours are applied) on a lime plaster which is still wet, the painting is called fresco (Italian word which means ‘fresh’). While painting a fresco, no binder is … Continue reading Frescoes vs Tempera

Conservation of wall paintings at Thakur Satyanarayan temple: a brief account
This hundred year old temple needed an uplift. It had wall paintings that were not clearly visible due to layers of grime and there was also heavy flaking to make the condition worst. The temple authorities had already tried a few artists to over paint the damaged paintings. The new over-painting of course looked brighter, but the quality and style were a big mismatch with … Continue reading Conservation of wall paintings at Thakur Satyanarayan temple: a brief account

It settles between the canvas and stretcher … Continue reading Treating the back of a canvas painting

Heritage Preservation Atelier conducted a 3 days Workshop/congress in Chandigarh
Heritage and its conservation/preservation are both not very well understood by us. This is understandable, because, we lag behind in care and understanding of even more important and basic areas of life, like environment, waste-management, religion etc. In any case, each and every profession has to develop and grow in a positive way irrespective of the situations around in other fields of work.

Wall painting conservation and restoration
Should the importance and value of painting or heritage object decide the methodology of conservation? How much time, efforts and money should be put in conserving or restoring it?
Some objects and art work is priceless because of its historic or cultural value. It is wise to make a highly trained and educated conservator do it’s conservation with most expensive conservation grade material taking days and days of labour. But, if the work is of value only to the owner and he/she want to do it in a way that is less expensive and … Continue reading Should the importance and value of painting or heritage object decide the methodology of conservation?

Archival conservation: a case study
Bookworms love spines of books and hate anoxic environment
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
Paper burnt or eaten?
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?
Removing Foxing is doable, but needs thorough understanding and patience too…
In paper conservation literature, there are many ways and materials advised to be used to remove foxing or at least lighten its scars.

The conservator must know … Continue reading Removing Foxing is doable, but needs thorough understanding and patience too…
Foxing
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

But, at a closer look and … Continue reading Some deteriogens are very nicely hidden
Brief record of miniature painting’s assessment and conservation
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
Flaking in Miniature Paintings
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
