Effect of Clay Pots Made from Red and White Clay on the Physicochemical Properties of Stored Water and Their Efficacy in Improving Water Alkalinity

This study aims to assess the impact of storage in earthenware vessels, fabricated from two distinct clay types (red and white), on the physicochemical properties of distilled water. A specific focus was placed on pH and alkalinity. The experimental procedure involved storing distilled water in both red and white clay vessels, with a glass container serving as a control sample. Measurements were subsequently acquired at predetermined intervals: 2, 6, 12, 24, and 48 hours. The analyses encompassed measurements of electrical conductivity, total dissolved solids, and the concentrations of various ions, including sodium, potassium, calcium, magnesium, chloride, sulfate, bicarbonate, and nitrate. Results demonstrated a notable increase in the pH of water stored in the clay pots when compared to the glass control, thereby indicating their capacity to modulate water alkalinity. Furthermore, measurements revealed alterations in the concentrations of certain ions and other physicochemical characteristics, attributable to the interaction between the water and the different clay types. This research contributes to the scientific documentation of the potential efficacy of clay pots as a sustainable and economical alternative for enhancing drinking water quality, particularly in terms of adjusting the water's basic properties.
