Production of chalk from eggshells

We noticed that the students and teachers consume many pieces of it, which is very expensive. Then wait for two to three days until the chalk dries.

Production of chalk from eggshells

This makes the product harmless to the human body, and its powder can be used directly as a soil conditioner for school vegetable and flower gardens. Dissolve — to become absorbed in a liquid solution. Effectiveness — the ability to do something well or achieve a desired result without wasted energy or effort. The one major type is limestone. Indigent — extremely poor, lacking the necessities of life. Eggshell is another object that has the presence of calcium carbonate. The components of chalk are so complex that it has the capacity to make other things beside chalk itself. The study is very efficient in these days because many people are in need of chalk especially the teachers because they use board chalks in school everyday. An eggshalk can also help make sure that the chalk is not toxic.

An eggshalk can also help make sure that the chalk is not toxic. Chicken eggshells contain calcium carbonate.

Egg shell chalk

A mixing bowl to mix the water, powdered eggshells and flour together, a sheet of hard paper to mold the chalk to a cylindrical shape, mortar and pestle to crush the eggshells into fine powder , weighing scale to measure the amount of grams of eggshell powder and flour, a beaker to contain the amount of hot water, a teaspoon to measure the amount of hot water to be added on the mixture. This will help them to save money on buying commercial chalks because they can make their own chalks at home using materials that is easy to find and very cheap. Pulverize — to crush or grind something into powder or dust. They also have the same qualities; like for example, they can break easily. We chose this study for further investigation if eggshells can be an effective source for chalk production. Significance of the study This study can give benefits to the community specially to the teachers, students and faculty members. The research specifically wanted to test out these questions : 1 Can eggshells be an alternative ingredient for making the eggshalk? While chalk is usually made from calcium sulfate or mined calcium carbonate, the newly developed chalk is made from eggshells, composed naturally of calcium carbonate. Indigent — extremely poor, lacking the necessities of life.

The company has expanded eggshell use to school supplies, supplying them as a raw material for blackboard chalk. Then heat a water in a beaker and add four teaspoons of hot water to the mixture of eggshell powder and flour.

We chose this study for further investigation if the eggshell can be an effective material for the chalk. Definition of Terms : The researchers defined the following terminology based on how it is used in the investigatory project.

how is chalk made

Flour — a powder made by grinding the edible parts of cereal grains. This will help them to save money on buying commercial chalks because they can make their own chalks at home using materials that is easy to find and very cheap.

Chalk recipe

We chose this study for further investigation if the eggshell can be an effective material for the chalk. They function as a special calcium carbonate. The product is only focused on one function which is for use in writing in a chalkboard. The Kewpie Group uses the largest amount of chicken eggs of any company in Japan, producing 23, tons of eggshells annually. Some birds like the chicken force the eggs out while some wait for some time until it is out. This study is only limited to the investigation of eggshells used as an alternative material used for making chalk. We use chalk in school everyday but the price of the chalk in stores are expensive so we decided to create an alternative board chalk made from eggshells which is cheaper and much easy to make. 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. It is also beneficial for the indigent, mountain people, public schools, and ordinary people because when they run out of chalk, they can apply their knowledge in making chalk by using the easy-to-find, cheap, and recyclable materials. It forms under reasonably deep marine conditions from the gradual accumulation of minute calcite plates shed belonging to the division of haptophytes. Significance of the Study : The purpose of this study is to help the students and faculty members discover methods to find cheaper and easy-to-do chalk using recyclable materials.
