Abstract
This study aimed to produce ink from Mahogany sawdust tannin. Specifically, it sought to determine the physical properties of ink using different amounts of glycerol as mordant; the physical properties of ink using different amounts of glycerol in terms of color, odor, and pH; the acceptability of the ink in terms of color, odor, and absorptivity; the best proportion of raw materials in the production of ink; and whether a significant difference exists in the physical properties of the inks in terms of pH. The study used the developmental and descriptive method that involved the production of ink, observation, and testing of the aforementioned properties, as well as a survey of the acceptability of the ink. One-way Analysis of Variance was used to determine whether significant difference exists in the pH of the inks produced using different amounts of glycerol. Findings of the study show that all three sample proportions were black, had a faint pleasant odor, and the pH values were consistent. The ink from Mahogany sawdust tannin was acceptable in terms of color, odor, and absorptivity. The best proportion of the raw materials in the production of ink is 10 milliliters tannin extract, 1 gram ferrous sulfate, 1 gram sodium chloride, 1 milliliter ethyl alcohol, and 3 milliliters glycerol. It has a darker color compared to the other two proportions containing 1 mL and 2 mL of glycerol, respectively. There is no significant difference in pH among the three ink samples containing different amounts of glycerol. The ink produced from Mahogany sawdust has been found very highly acceptable.
