I. Problem: Will natural dyes from plants effective in producing colored paste? II. Title: Using Natural Dyes form Plants In Producing Colored Paste III. Introduction:
Our project is made from the raw materials such as starch, alum and annatto seeds. One of our reasons in making this project is it can help students save money because our product can be a substitute for glue. It doesn’t cost us too much time because we can make this in a short period of time. IV. Review of Related Literature: * Our project is somewhat similar with the project of other students from Manresa School Paranaque City. It is about dyeing of fabric through the use of NATURAL DYES FROM PLANTS. CONTENTS OF THEIR PROJECT:

One mL of liquid fabric detergent is added to the mixture. The solution was boiled for 30 minutes. The cotton cloth was soaked in the solution and the solution was boiled again for 30 minutes. The bleached or scoured material was washed with warm water twice. The cloth was rinsed thoroughly with tap water and air-dried.

Mordanting Mordants (alum and copper sulfate) were dissolved separately in water to make a 5 percent solution (1 gram mordant per 20 mL water). The pretreated material is submerged in the prepared solutions and allowed to dry. Cloth Dyeing The mangosteen dye extract was poured into a basin and the mordant- treated material was soaked in the dye. The dye, together with the cloth, was boiled for two hours. During heating, it was ensured that the cloth was completely submerged in the dye for the entire duration to attain even dyeing. The dyed material was then rinsed thoroughly with tap water. Dyed materials must be rinsed thoroughly to prevent bleeding or staining. After dyeing, the material was air-dried.

RESULT HIGHLIGHTS During the dye extraction process, it was noticed that the surface of the boiling mixture became lighter in color. After two minutes, at a temperature of 91 degrees Celsius, a yellowish-green precipitate was formed. At the end of the process, the mixture became dark brown with yellowish
