In the accomplishment of this project successfully, many people have best owed on me their heart pledged support. I am utilizing
this opportunity to thank all the people concerned with this project.
Primarily I would like to thank my principal Mrs. Srividya Mouli and my chemistry teacher Mr. Peter Paul, whose valuable guidance has been the ones that helped me patch this project and make it full proof success. His suggestions and instructions have served as the major contribution towards the completion of this project. I
would also like to thank my classmates for their support. This project will not be complete without acknowledging the help of
AIM OF THE PROJECT:
To find out if tea bags can be used to create ink, and to produce an ink as cheaper alternative to the commercial ones.
Tea was 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 in fact 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. 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. 2
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.
Generally, this investigatory project aims to find out if tea bags can be used to create an ink. Specifically, it aims to find out the answer to the following questions:
1. Can vinegar strengthen the color of the ink?2. Can cornstarch contribute to achieving the right consistency of the Ink?3. Are the processes boiling and straining efficient in taking the extract out of the tea bags?
4MATERIALS REQUIRED: 1 cup of water 7 tea bags 1 tsp of vinegar
Strainer and fork
1. place 7 teabags in 1 cup of boiling water.
2. create the tea for 6-7 minutes.
3. remove the tea bags from the boiling water. Use a strainer and a fork to remove all the extracts.
4. stir the tea well, and add a spoon of vinegar.
5. continue to stir it. Add as much cornstarch as you need to have your desired consistency.
6. remove the mixture from the heat and let it cool for sometime. When done Store it in a bottle.
During the procedure itself, it was observed that the boiling is an effective process of extraction. Right after the tea bags were placed in the boiling water, the change of colour is very noticeable. During this step the mixture had a very strong smell from the tea. While following the procedure for the set up which included the placing of vinegar, there was no immediate change in colour as we expected. Instead, the vinegar’s effect was seen when the ink was applied on paper. While applying the ink on paper, It was easier to use the ink because of it’s consistency. Thus it almost became permanent and not runny and scattered. After letting them dry, it was seen that the ink had darker colour and doesn’t fade.
1. Tea bags can be used to create an ink.
2. Vinegar can strengthen the colour of the ink.
3. Cornstarch effectively contributes to achieving the right consistency of the ink.
4. The process of boiling and straining are efficient in taking the extract out of the process.
