Here's a breakdown:
* Scientifically, clays are classified based on their mineral composition. Common clay minerals include kaolinite, montmorillonite, illite, etc. So, an oil-based clay might be made with kaolinite, but there's no special scientific name that combines "kaolinite" with "oil-based".
* The term "oil-based clay" is a descriptive term used in the art and craft industry. It helps distinguish it from other types of clay like water-based clay or polymer clay.
Therefore, while you might find specific mineral names for the clay component of an oil-based clay, there is no single scientific name for the entire material.
