Since we are talking about wooden slates, those who must have used wooden slates (Takhti) must be knowing that there are two ways of doing this:
1. First way is to smear the surface of slate with a suspension of white clay, allow it to dry and then wright with normal ink using wooden pen (kalam)........black/blue black on white. 2. Second way includes moving slate over a flame of oil lamp in such a way that it gets covered with soot. The next step is to rub the fresh leaves of Rumex so that the soot sticks firmly on the slate, and then rub back of inkpot on the slate to give it a shine (ghota). This black slate is then written on using the suspension of white clay.........white on black Lucky for modern children, no messing around and no hard work. simple slates and crayons, most self rubbing/easing rubbing. -- Dr. Gurcharan Singh Retired Associate Professor SGTB Khalsa College, University of Delhi, Delhi-110007 Res: 932 Anand Kunj, Vikas Puri, New Delhi-110018.
