Tea is created by using the leaves of a plant known as Camellis sinensis . This plant is a native to China, South Asia and Southeast Asia but is now found Tea-drinking can be traced back to the 10 century BC in China before it was spread to Korea and Japan. Basically, this drink is made by brewing tea leaves to create an extract. Due to the chlorophyllsand other pigments in the leaves, the extract commonly appears with a brown color. It was mentioned that the aflavin is the reddish brown pigment found in tea. It is an example of a flavonoid which acts to create color. OBJECTIVES

This research is being done to find out the potency of the extract of the leaves from the plant Camellis sinensis as an ink. Nowadays, ink is a pigment in a liquid or paste form used as colorants and dyes. Also, they are becoming more and more expensive because of their increasing purposes. Our research aims to produce this ink as a cheaper alternative to those commercial ones. Compared to the ink we are aiming to create, commercially produced inks are toxic and can be hazardous to a person’s health once there is inappropriate contact with it. To match with the color and consistency of other inks, we will be adding other substances, specifically vinegar and cornstarch, which are common and easy to find. STATEMENT OF THEPROBLEM

Generally, this investigatory project aims to find out if tea bags can be used to create an ink. Specifically, it aims to answer the following questions: A. Can vinegar strengthen the color of the product, ink? B. Can cornstarch contribute to achieving the right consistency of the ink? C. Are the processes boiling and straining efficient in taking the extract out of the tea bags? HYPOTHESES

Extracts taken from tea bags have the potential to be made into an ink. If vinegar and cornstarch are added to the mixture, then the product would have a stronger color and a thicker consistency. SIGNIFICANCE OF THESTUDY

This investigatory project will benefit us by producing an alternative for other inks. These other manufactured inks nowadays come quite expensive prices, but since the materials to be used in our project are common and easy to find, you will be spending less money. Also, no harmful chemicals will be used in making our ink. Therefore, it is non-toxic compared to commercially sold inks which have the tendencies of causing harm to one’s health and to the environment.

Our research and experiments are only limited to making a simple ink as a colorant. It does not include inks that are used in machines such as printers, copiers, etc. Also, our study includes the effects of vinegar and cornstarch on the product. To have accurate observations, we will be creating two set-ups: an ink without vinegar and cornstarch and one with vinegar and cornstarch. REVIEW OF RELATED LITERATURE

The history of Chinese inks can be traced back to the 18th century BC, with the utilization of natural plant dyes, animal, and mineral inks based on such materials as graphite that were ground with water and applied with ink brushes. The India ink used in ancient India since at least the 4ath century BC was called masi, and was made of burnt bones, tar, pitch, and other substances applied with sharp pointed needle. Saffron is well known as the source of a truly brilliant if rather fugitive yellow and there is evidence of its use, both as a colorant and medicine, in the Greek and Persian civilizations of the same period. Indian skill in vegetable dyeing and painting reached a high point in the two centuries from 1600 to 1800 AD, when the painting and resist dyeing of cotton cloth known to us as Chintz became the basis of the largest trade in textiles that the world had ever seen. The Strasbourg manuscript, of an earlier period, also describes the use of a whole range of plants used...
