Can you use olive oil instead of vegetable for homemade clay?

No, olive oil cannot be used instead of vegetable oil for homemade clay. Vegetable oil is a common binding agent used in clay recipes due to its non-drying properties, which allow the clay to remain workable and pliable. Olive oil, on the other hand, is a drying oil, which means it solidifies and hardens over time. This drying characteristic makes olive oil unsuitable for use in homemade clay, as it would cause the clay to become brittle and difficult to work with.
