The kohl I made is from an ancient Indian recipe, which I obtained from a friend's grandmother. It combines the soot of an oil lamp with castor oil. The materials for this project were few, all that was required was: an oil lamp with wicks, an iron plate and a few drops of castor oil. To make the invention, I held the iron plate above the burning oil lamp, where, after an extremely long amount of time, a black powder (the soot) began to collect at the edges. When a sufficient quantity of soot had been collected, a few drops of castor oil were mixed in until the consistency was that of a solid caked paste. The final product was then placed in a decorative bowl. While making kohl is a relatively simple process, it is nonetheless a very time consuming one. If you plan on doing it, make sure you have someone to keep you company! Strict caution had to be exercised to ensure that no dust or other foreign particles adulterated the soot gathered from the iron plate since the kohl is to be used to line the insides of the eyes.
