Are the insulating properties in sugar strong enough to counteract the conductivity of table salt? The objective of this experiment is to figure out how different increments of sugar can affect the conductivity of a conductive clay wire. Our interest for clay crafting and a recent study of elements inspired this experiment, as salt is a commonly listed ingredient in a variety of clay formulas as the preserver. We incorporated sugar to determine if including it as one of the ingredients could cancel out the table salt and affect the properties of the clay. Salt and water produces the ability to pass electricity, while sugar causes the opposite effect. We began by weighing all the ingredients on a food scale. After mixing the mixture thoroughly, we cooked it on medium heat and molded a cylindrical shape seven centimeters long and four and a half centimeters wide. The first clay was created with only salt, and increased the sugar in increments of five grams with each batch and measured the resistance with a multimeter. We calculated for the conductivity. Comparing the control group with the experimental groups’ results, we came to a conclusion that with each addition of sugar came a decrease in conductivity. With our experiment findings, this information could help further develop the creation of wires in the real world applications. A wire with more ionic bonds than covalent bonds allow energy to flow smoother. Hence, when the wire is being constructed for conductive purposes, it should be built of pure material with only ionic bonds for maximum conductivity.
