c4.s7.t1.3

The ASI has taken the responsibility for making the impressions of these unique and often fragile Harappan objects. The use of silicone rubber was considered, but in their tests the chemists of the ASI came to the conclusion that the condition of the objects does not allow this material to be used. Unfortunately the plasticine used instead is not sensitive enough, so that all details have often not been reproduced. Moreover, small crevices often form when a forceful impression is made on plasticine, with a result that is not aesthetically pleasing even if it may otherwise be adequate (cf., e.g., M-32 a & M-208 a). And in the case of large seals especially, it is difficult to obtain a good impression in which all parts of the inscription and the device are perfect. However, in the vast majority of the seals, the new impression is much better than the old one.
