Introduction
Tea is an beverage originated in China. After water, it is the most widely consumed drink in the world. It is commonly prepared by pouring hot or boiling water into a cup with cured leaves of Camellia Sinensis. It is an evergreen shrub or a small tree that is usually trimmed to below 2 m (6.6 ft.) when cultivated for its leaves. The flowers are yellow-white in color, 2.5-4 cm (0.98-1.6) in diameter, with 7 to 8 petals. It also has a strong taproot. This kind of plant is native to mainland China, South And Southeast Asia but now, it can be found across the world in tropical and subtropical regions. Tea drinking can be traced back to the 10th Century BC in China before it was spread to Korea an Japan. Basically, tea is made by brewing tea leaves to create an extract. Due to the chlorophylls and other pigments the leaves contain, the extract commonly appears with a brown color.
Ink is a liquid or paste that contains pigments or dyes and is used to color a surface to produce an image, text, or design. Ink is used for drawing or writing with a pen, brush, or quill. Thicker inks, in paste form, are used extensively in letterpress and lithographic printing.
Ink can be a complex medium, composed of solvents, pigments, dyes, resins, lubricants, solubilizers, surfactants, particulate matter,fluorescents, and other materials. The components of inks serve many purposes; the ink’s carrier, colorants, and other additives affect the flow and thickness of the ink and its appearance when dry.
Other residences in province can make their own ink because school supply stores are too far from their houses. This study aims to search for a natural and renewable source of ink, to look for a cheaper way of producing ink with the use of tea bags, to create an alternative resource and methodology of producing ink, to generate a nontoxic form of ink
