Hypothesis:

1. there is no significant difference on the effectiveness of the coloring material based on the application to different types of paper.

Materials:

1. camote leaves extract
2. crushed white candles
4. cheesecloth
5. mortar and pestle
6. beaker
7. vegetable oil

The Procedure:

Collection and Preparation

The camote leaves were gathered early in the morningto preserve its freshness. Before extraction, it was washed in a tap water to remove unwanted insects and particles. Then it was strained to remove the excess water. The extraction process begins.

Production of Coloring Material

The extract was obtained by pounding the leaves with mortar and pestle and strained with a cheesecloth. In a 100g of camote leaves, the extract only reached 50ml in a 600ml beaker. The extract was mixed with 100mg of crushed white candle and three drops of vegetable oil. After mixing, the extract was heated to dissolve the candle and stirred thoroughly until the colored solution was mixed with the wax. After the wax turned green, unmixed color were separated by a cornstarch. Cornstarch absorbs water content on the extract. The colored wax was poured on the molder.

Results:

The result shows that the effectiveness of the product produced depend on the thickness of the paper. the thicker the paper, the more visible is the color and the thinner the paper, the lighter is the color and vice-versa.
The color produced was only color-green.
