Conclusion
A dense, carbon black ink has been successfully reproduced based on a Malay traditional recipe
originated from Pasir Mas, Kelantan. The black ink comprised of soot and mangosteen charcoal as the
colourant, cashew gum as the adhesive or vehicle, black pepper, virgin coconut oil and salt as additives,
and distilled water as the solvent. Their respective composition is 4 g soot, 4 g mangosteen charcoal, 2 g
cashew gum, 3 g black pepper, 0.1 ml virgin coconut oil, 0.5 g salt and 100 ml distilled water. This
formulation has been screened upon undergoing a series of qualitative and quantitative evaluations. The
