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?
