New International Webster’s Pocket Dictionary Essay

Egg, as we all know, is one of the most common food ingredients. It is used mostly in cakes, Lech flans, and omelets. It is also used in many other recipes like mamas, appaloosa, razor valerian, among others. The parts of the egg that we consider useful are only the yolk and the white. These are the parts of the egg used as food ingredients. The eggshell is often considered as useless. Usually, this part of the egg is thrown away after the eight and yolk are taken from it and used.

Although, there are mom who used eggshells as ornaments, they are few, and this practice is not common. Study shows that the eggshell contains calcium carbonate – a form of limestone that can be converted to chalk – that material that we use in writing on the blackboards. The purpose of this research is to produce a chalk that is non-toxic and therefore safe for school children, teachers, and other people who use chalk in their activities. The success of this study will contribute to the health of the general public.

The sidewalk chalk from an eggshell can be used in various ways by many people such as students, teachers, and anyone who wants to use it. Unlike the common chalk which is used at school, this sidewalk chalk will not produce dust which can be harmful to the health because it has no calcium sulfate which produces the chalk dust. According to Wisped, chalk, marble, and limestone are all forms of calcium carbonate. Calcium carbonate (Cacao) is one of the common compounds of calcium. It is heated to form quicklime (Cacao), which is then added to water (H2O).

This forms another material known as slaked lime (Ca(OH)2), which is an inexpensive base material used throughout the chemical industry including the chalk that we use every day. Since according to study, the egg shell contains high level of calcium, it can be processed using water and certain carbon compound to produce chalk. The advantage of the chalk that may be produced from egg shell is that it is harmless to people due to its being non-toxic. The researchers did not use the components of the ordinary chalk that produce dust since it may cause health problems to anyone who could inhale or ingest them. Wee By Rosemary
