Topics: Tea bag, Tea, Water Pages: 5 (1698 words) Published: March 5, 2013
Background of the Study Tea is created by using the leaves of a plantknown as Camellis sinensis. This plant is native tomainland China, South and Southeast Asia, but it istoday cultivated across the world in tropical andsubtropical regions. It is an evergreen shrub orsmall tree that is usually trimmed to below 2 m(6.6 ft) when cultivated for its leaves. It has astrong taproot. The flowers are yellow-white, 2.5-4cm (0.98-1.6 in) in diameter, with 7 to 8 petals. 2. Tea-drinking can be traced back to the 10thcentury BC in China before it was spread toKorea and Japan. Basically, this drink is madeby brewing tea leaves to create an extract. Dueto the chlorophylls and other pigments in theleaves, the extract commonly appears with abrown color. 6. OBJECTIVESThis research is being done to find outthe potency of the extract of theleaves from the the plant Camellissinensis as an ink. Nowadays, ink is apigment in a liquid or paste form usedas colorants and dyes. Also, they arebecoming more and more expensivebecause of their increasing purposes. 7. Our research aims to produce thisink as a cheaper alternative tothose commercial ones. Comparedto the ink we are aiming to create,commercially produced inks aretoxic and can behazardous to apersons health once there isinappropriate contact with it. 8. To match with the color andconsistency of other inks, wewill be adding other substances,specifically vinegar andcornstarch, whichare commonand easy to find. 9. STATEMENT OF THEPROBLEMGenerally, this investigatory project aimsto find out if tea bags can be used tocreate an ink.Specifically, it aims to answer thefollowing questions:a. Can vinegar strengthen the color ofthe product, ink?b. Can cornstarch contribute toachieving the right consistency of theink?c. Are the processes boiling andstraining efficient in taking the extractout of the tea bags? 10. 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 than 11. SIGNIFICANCE OF THESTUDYThis investigatory project will benefit us byproducing an alternative for other inks.These other manufactured inks nowadayscome quite expensive prices, but since thematerials to be used in our project arecommon and easy to find, you will bespending less money. Also, no harmfulchemicals will be used in making our ink.Therefore, it is non-toxic compared tocommercially sold inks which have thetendencies of causing harm to ones healthand to the environment. 12. SCOPE ANDLIMITATIONSOur research and experiments areonly limited to making a simple ink asa colorant. It does not include inksthat are used in machines such asprinters, copiers, etc. Also, our studyincludes the effects of vinegar andcornstarch on the product. To haveaccurate observations, we will becreating two set-ups: an ink withoutvinegar and cornstarch and one withvinegar and cornstarch. 13. REVIEW OF RELATEDLITERATUREThe history of Chinese inks can be tracedback to the 18th century BC, with theutilization of natural plant dyes, animal,and mineral inks based on such materialsas graphite that were ground with waterand applied with ink brushes.The India ink used in ancient India since atleast the 4ath century BC wascalled masi, and was made of burnt bones,tar, pitch, and other substances appliedwith sharp pointed needle . 14. Saffron is well known as the source of atruly brilliant if rather fugitive yellow andthere is evidence of its use, both as acolorant and medicine, in the Greek andPersian civilizations of the same period.Indian skill in vegetable dyeing andpainting reached a high point in the twocenturies from 1600 to 1800 AD, whenthe painting and resist dyeing of cottoncloth known to us as Chintz became thebasis of the largest trade in textiles thatthe world had ever seen. 15. The Strasbourg manuscript, of anearlier period, also describes the use ofa whole range of plants used in themanufacture of inks...
