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 all over the world. Tea-drinking can be traced back to the 10th century BC in China before it was spread to Korea and Japan.

But in 1903, the creation of the first tea bags were recorded. It was then in 1904 that these were shipped around the world and they are infact still used until now. They are not only cheaper, but also they easier to find and to use in making tea.

The reason for their more affordable price compared to loose tea leaves is because most companies use fannings or left-overs of larger tea leaves after they are gathered to be sold.

Basically, this drink is made by brewing tea leaves to create an extract. Due to the chlorophylls and other pigments in the leaves, the extract commonly appears with a brown color.

In www.webexhibits.org/causesofcolor/7H.html, 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.

This reaserch 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.
