imbestigatory project imbestigatory project Document Transcript

  • Background Tea is created by using the leaves of aplant known as CAMELLIS sinensis. This plant is native to mainland china , south and southeast asia , but it is today cultivated across the world in tropical and subtropical regions . It is an evergreen shrub or small tree that is usually trimmed to below 2 m (6.6ft) when cultivated for its leaves. It has a strong taproot . The flowers are yellow-white , 2.5-4cm (0.98-1.6) in diameter , with 7 to 8 petals. Tea drinking can be traced back to the 10th century BC in china before it was spread to korea and japan. Basically, this drink is made by brewing tea leaves to create and extract. Due leaves, the extract commonly appears with a brown colors
  • OBJECTIVES This research is being done to find out the potency of the extract of the leaves from the extract leaves from the plant CAMELLIS sinensis as ink. Nowadays, ink is 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 a inappropriate contact with it. To match with the color and consistency of other inks, we will be adding other substances, specially vinegar and cornstarch, which are common and easy to find.
  • STATEMENT OF THE PROBLEM Generally, this investigatory project aims to find out if tea bags can be used to create an ink. Specifically,it aims to answer the following questions: 1.Can vinegar strengthen the color of the product, ink? 2.Can cornstarch contribute to achieving the right consistency of the ink? 3.Are the processes boiling and straining efficient in taking the extrct out of the tea bags?
  • HYPOTHESIS OF THE STUDY 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 thicker consistency than to an ordinary ink.
  • SIGNIFICANCE OF STUDY This imbestigatory project will benefit us by producing an alternative for other inks. This other manufactured inks nowadays come quite expensive prices, bit since the materials to be used in our project are common and easy to find , you will be spending less money. Also, no harmful chemical s will be used in making our ink. Therefore, it is non-toxic compared to commercially sold inks which haves the tendencies of causing harm to one’s health and to the environment.
  • SCOPE ANG LIMITATIONS Our research and experiments are only limited to making a simple ink as a colorant. It does not include inks that are used in machines such as printers, copier ,etc.Also, our study includes the effects of vinegar and cornstarch on the product. To have accurate observations, we will be creating two set-ups: an ink without vinegar and cornstarch and one with vinegar and cornstarch.
  • REVIEW OF RELATED LITERATURE This history of Chinese inks can be traced back to the 18th century BC, with the utilizations of natural plant dyes,animal and mineral inks based on such materials as graphite that were ground with water and applied with ink brushes.The india ink used in ancient india since at last the 4ath century BC was called masi, and was made of burnt bones , tar, pitch and other substances applied with sharp pointed needle . Saffron is well know as the source of truly brilliant if rather fugitive yellow and there is evidence of it’s use, Persian civilizations of the same period.Indian skill in vegetable dyeing painting reached a high point in the two centuries from to 1600 to 1800 AD, when the painting and resist dyeing of cotton cloth known to us Chintz became the basis of the largest trade in textiles that the world had ever seen.
  • The Strasbourg manuscript of an earlier period, also describes the use of a whole range of plans used in the manufacture of inks and water-colours. Later we see developments in vegetable block-printing inks in 17th and 18th century japan where it is interesting to note the some colours were actually leached from previously dyed cloth. Early historical accounts of tea are uncleare for the Chinese character for tea had not been standarlized and several other Chinese characters appear in books referring very likely to the same plant,camellia sinensis, what we now call tea. Tea dyeing is an easy way to mute fabrics or give them an older, antiqued look. Tea stains the fibers and gives a semi- permanent dull brown ‘dirty’ tone to the whole piece.it used when you want to ‘antique’ a craft textile such as adoll dress or small quilt.
  • METHODOLOGY MATERIALS: 7 tea bags 1 ½ cups of water 1 tablespoon of vinegar Cornstarch Strainer and fork Bottle PROCEDURE Place the 7 teabags in 1 ½ cups of boiling water. Create the tea for 6-8 minutes.
  • Remove the tea bags from the boiling water. Use a strainer and a fork to remove all the extracts. While stirring the tea, add a tablespoon of vinegar. Continue to stir it. Add as much dissolved cornstarch as you need to have your desired consistency. Remove it from the heat and let it cool. When done, store in a bottle..
  • FINDINGS During the procedure itself, we have observed the boiling is an effective process of extraction. Right after we have placed the tea bags in the boiling water, the change of color is very noticeable. During this step the mixture had every strong smell form the tea. While following the procedures for the set ups A which include the placing of vinegar, there was no immediate change in color as we expected. Instead, the vinegar effect was seen when we tried to paint the two inks on paper. While applying the ink on paper, it was harder to use ink B because it’s consistency was very watery. Thus it became runny and scattered unlike ink A.
  • DISCUSSION OF RESULTS Our hypothesis which states that teabags have the potential to be made into an ink if vinegar and cornstarch is added is proven correct. We had two set-ups which were set up A that has vinegar and set up B that has no vinegar. Vinegar is mainly a dilute aqueous sulotion of acetic acid which is an important reagent and industrial chemical, mainly used in the production of cellulose acetate. A cellulose acetate is used as film base in photography and a film is a transparent substances which acts as a support medium for the photosensitive emulsion that lies a top it, it’s base generally accounts for the vast majority of the thickness of any given film stock.
  • The addition of vinegar and cornstarch in making an ink can result to a thicker consistency and consistent color which is better for the usage of the ink. Our observation prove that adding vinegar to the mixture can be made into an ink because without the vinegar there would be no consistency on the mixture and it be less seen.
  • SUMMARY There are many different kinds of ink. In our experiments we will use tea bags as the main component of out ink. Having two different set ups will provide the chance to compare the colors and consistencies. Cornstarch is an efficient additive to have the right consistency of the product. Also vinegar is also efficient, through there is no obvious change in color, it was seen that it gave the ink a consistent color wether were dry.
  • We therefore conclude the one can create an improvised ink using the extract from tea bags. This will be very convenient and cheap because the ingredients to be used are commonly found around the house. Also, the said processes, boiling and straining, are ca be easily done.
  • CONCLUSION Tea bags can be used to create an ink. Vinegar can strengthen the color of the product, ink. Cornstarch effectively contributes to achieving to the right consistency of the ink. The processes boiling and straining are efficient in taking the extract out of the tea bags.
