👉 Holotony is a scientific term that refers to the phenomenon of two or more different materials or substances having similar or identical physical properties, but with distinct chemical compositions. It can be defined as a state where at least one material in the mixture has a higher concentration than the other. For example, if you have two different types of clay mixed together, such as a white clay and a black clay, each clay would have a slightly higher concentration than the other because of differences in their chemical compositions.
