Research Study on Ink and Teabags
Transcript of Research Study on Ink and Teabags
Charles de los Santos
Tea is created by using the leaves of a plant known as
is the reddish brown pigment found in tea. It is an example of a
which acts to create color.
Produced inks are toxic and can be hazardous to a person’s health once there is inappropriate contact with it.
We'll be adding other substances, specifically vinegar and cornstarch, which are common and easy to find.
Can vinegar strengthen the color of the product, ink?
Can cornstarch contribute to achieving the right consistency of the ink?
Are the processes boiling and straining efficient in taking the extract out of the tea bags?
of the study??
Scope and Limitations
effects of vinegar and cornstarch on the product
we will be creating two set-ups:
-an ink without vinegar and cornstarch
-and one with vinegar and cornstarch.
making a simple ink as a colorant
does not include inks that are used in:
Review of related literature
it speaks of.....
the ancient Egyptians and the Chinese, both developed ink at approximately the same time around 2500. B.C.
They used fine particles of carbon called lampblack for the colorant, and gums or glues were the vehicles.
Ink and its production has always been to a certain extent problematic, it has always had issues regarding durability, it fades when exposed to sunlight and different types of paper absorb different amounts of ink.
Between the eighth and the eleventh Century, a chemical ink, iron gall ink developed from tannic acid and iron salt; it became a popular colorant bound by resin.
This development itself has revolutionized many aspects of the printing business not least of which in the sign industry.
SET-UP B MATERIALS:
1 1/2 cups of water
Results and Discussion
the ink in setup A is DARKER and the CONSISTENCY is more potent
and set up B lacks in consistency and color
Background of the Study
when extracting ink from tea bags boiling it will be an effective process
Tea bags can be used to create an ink.
Vinegar can be used to strengthen the color of the ink
The usage of cornstarch effectively achieves the desired consistency of the ink. Straining and boiling are effective ways in taking the extract out of the tea bags.
Longer time of extraction (boiling and straining)
Make sure to add a generous amount of cornstarch so that the application of the ink will be easier
Make use of items other than household items like gum Arabic, soybean oil, etc
