During olden times when sroops were written, gursikhs also made their own ink. Over time they wrote this ink recipe at the end of SGGSJ which many assumed was Gurbani, but later this bani was removed. Does anyone have Shiyahi di vidhi bani, or atleast the ink recipe it contained. I think it would be interesting to make ones own ink like puraatan times and write Gurbani using that ink.
