It is often required to compare the depth of colors of solid matters in homemaking studies. The colorimeter is widely used, but it is difficult to use it in school education for financial reasons. So, usually a visual comparison is made and the results are recorded subjectively. Because of the reasons mentioned above, a trial production of a simple colorimeter was attempted. Also, we studied the relation of the concentration of detergent to detergency, and the concentration of bleaching agent to bleaching efficiency; we also researched how to prevent cut ends of apples from browning, using the trial apparatus. As a result of these studies, a close agreement between experimental results measured by this trial colorimeter and results measured by the colorimeter on sale were obtained. The availability of the trial colorimeter was thus confirmed.
