* Mineral composition: Some minerals, like serpentine or jade, have a naturally waxy or greasy feel.
* Surface finish: A polished surface can feel waxy, even if the underlying rock is not.
* Impregnation: Some rocks might have been treated with wax or other materials that create a waxy texture.
* Weathering: Certain types of weathering can create a waxy or slick surface.
To help identify the rock, please provide more information, such as:
* Color: What color is the rock?
* Hardness: Is it hard or soft? Can you scratch it with your fingernail?
* Location: Where did you find the rock?
* Any other features: Does it have any distinctive patterns, colors, or textures?
With more information, it might be possible to narrow down the possibilities and determine what kind of carved rock you have.
