The African elephant can be an effective way of saving the artificial ceramic ball. Unlike the plastic substitute, the ceramic is porous and looks more like the ball.
Natural boli is very similar to dentin, which is the component of human teeth. The boli to the touch is cold, at the same time soft, being able to be worked and polished until getting a smooth surface. For example, pianeros like because the porous structure absorbs sweat.
Today's artificial pellets are based on plastics. But their small erosions and inability to absorb sweat make them desirable from contact.
The University of Nottingahm is developing a new ceramic based material that will simulate the conductivity and porosity of boli.
According to conservationists, being a good substitute for the ball can eliminate the lives of many elephants from the clutches of furtibos.
