Background of the Study
The Research is about the effectiveness of eggshells as an alternative ingredient in chalk production. The study is very efficient in these days because many people are in need of chalk. The components of chalk are so complex that it had the capacity to make other things beside chalk itself. The chalk is a white porous sedimentary rock, a form of sedimentary rock composed of mineral calcite. It forms under reasonably deep marine conditions from the gradual accumulation of minute calcite plates shed belonging to the division of haptophytes. They function as a special calcium carbonate. Eggshell is another object that has the presence of calcium carbonate. It is used by animals to store their young in it and protect it. Some birds like the chicken force the eggs out while some wait for some time until it is out. The chicken egg is usually made as human food, and the others are left alone to give birth to life. The importance of conducting this research is that if the researchers succeed in looking for an alternative source for chalk, it would be easier to make one piece of it and it could contribute a lot of good things to waste management. Statement of the Problem

The Study aims to discover the effectiveness of eggshells in producing chalk in terms of the chalks Whiteness, Durability, Texture, and its writing capabilities. Hypothesis
The Study has concluded that eggshells can be an alternative ingredient in chalk production for it has same chemicals that are used in commercial chalk production. Scope and Limitations
The Study is only limited and focused on the investigation of Chicken Eggshells(Gallus Domesticus) used as an alternative source for chalk production. The...
