Sorry for the very late reaction. Perhaps my contribution could be useful :

« Relecture et techniques de correction dans les manuscrits indiens: L’exemple des manuscrits sanskrits philosophiques du fonds Chandra Shum Shere », in Christian Jacob (ed.), Lieux de savoir 2: Les mains de l’intellect, Paris: Albin Michel, 2011, p. 494-521.

It deals with the two phases of correction of paper manuscripts and with scribal techniques of cancelling, emending, adding, etc., and is illustrated. However it does not identify the substance of the paint used to cancel words and sentences.

Dear All,
 

I have been considering the ways in which scribes made corrections in the manuscripts they were copying, specifically in numerical tables.  Of course, there are a variety of practices that  (some are neater than others!).  One way of interest is the use of what appears to be (in the colour copies of manuscripts I have) a yellowish paste or paint (an early version of modern day “white-out” or “twink”?) which can then written over.

 

I attach a couple of examples. (The first example it has been used along several successive values in the third row, and in the second an entire column as well as individual entries.)

 

Does anybody know more about this technique?  What was the substance used?  How widespread is this?  Where can I read more about this?

 

With best wishes,

Clemency
