Actual test of the ink was done on permanent ink containers. Mayana leaves were gathered from Bureau of Plant Industry and Saba peelings were collected from different markets in Caloocan City. This study did not cover cost analysis of permanent inks since the focus of the study is to identify the feasibility of producing permanent inks using the said materials.

CHAPTER II
REVIEW OF RELATED LITERATURE

Ink, any liquid or viscous pigmented substance used for writing, printing, or drawing. The composition and consistency of an ink vary according to the purpose for which it is used. All inks, however, contain two rudimentary components: a pigment, or dye, called a colorant; and a vehicle, a liquid into which the colorant is dispersed. The more common types of ink include writing inks, drawing inks, printing inks, and invisible or sympathetic inks. Many inks differ from paints only in the purposes for which they are used.

The earliest writing inks were compounded of lampblack and a gum or glue and were mixed with water before use. Such inks are called India inks and are virtually permanent because the carbon in the lampblack is chemically inert and is not bleached or otherwise affected by sunlight. Colored India inks contain synthetic dyes rather than lampblack. India inks are primarily used for drawing (“Ink”, Microsoft Encarta Reference Library, 1992-2003)

The most permanent black ink is iron-gall ink, made by
