%X Kajjali (Black Sulphide of Mercury) is a Sagandha (together with sulphur), Niragni (fire is not involved in the process) Parada yoga (mercurial preparation). The Bandha (bond) involved in this preparation is Kajjali Bandha, where purified Parada (mercury) and Gandhaka (sulphur) are thoroughly ground in definite proportion, to get a fine black powder called Kajjali. Among Khalviya rasayana (mortar pestle apparatus used medicinal preparations), Kajjali is having prime importance as it forms base to many mercurial preparations. Though Ancient scholars mentioned some quality checks and end points in preparing Bhasma like Varitaratva, Rekhapurnatva, etc., these are not sufficient in the present scenario. Apart from these testing procedures, there is need of more sophisticated testing methods for determining the quality of Kajjali. The Present work illustrates the chemical characteristics of Kajjali obtained by well-defined process in the Ayurvedic classics. This Kajjali was evaluated by Scanning Electron Microscopy (SEM) and Energy Dispersive X-Ray Analysis (EDAX). SEM images with the magnifications of 2.00KX, 1.00 KX and spatial resolution of 25 nm represented that it formed the order of agglomerates consisted of small spherical particles approximately size of 3 ¦Ìm to 10 ¦Ìm observed, whereas EDAX showed the presence of Hg (69.33%), S (24.44%), O (4.64%) and Ag (1.59%) in the final preparation of Kajjali.
