Chalkeeper Prototype to Produce Chalk Out of Chalk Dust

Abstract

INTRODUCTION

From the Yanko Design (YD), the Chalkeeper concept was made and designed by Yonggu Do and Eunha Seo. According to Seth (2011), It is a duster that absorbs the chalk erased from the board and molds the dust back to a piece as the amount of gathered dust is enough. However, there is no actual machine yet that can execute the said concept. Thus, this study was conducted to determine the possibility of producing chalk by observing the chalk's physical properties in terms of its color and texture.

METHODS

This experimental research was conducted at the researcher's residence. First, the Chalkeeper prototype was made and adjusted to perform its purpose. Second, the machine was used to collect chalk dust from a chalkboard. Treatments were then prepared by mixing, in which the chalk dust was varied and water (5mL) being constant; T1 -5 grams; T2 -10 grams; and T3 -15 grams. Next, the molding process began by turning on the machine for 1 hour on each treatment. Afterward, treatments were then sealed and stored in a container.

RESULTS

The data from the experiment were interpreted through observation by the researchers to assess the physical properties of the produced chalk in terms of its color and texture. The observation was done by comparing the treatments to the commercial chalk. As a result, all treatments possessed all of the said physical properties of the commercial chalk with the T3 being the best among the treatments. With its white color and dusty texture, the third treatment was observed as the closest resemblance of commercial chalk among the treatments. On the other hand, T1 was proved to be the treatment that was the least similar to the commercial chalk.

DISCUSSIONS

These results proved that there is a possibility of producing chalk out of chalk dust by means of using the Chalkeeper prototype machine. Therefore, these results confirmed that the treatment which has a higher amount of chalk dust while with the amount of water being constant is better in terms of its physical properties specifically in its color and texture.
