Thread: Has anyone seen anything like this before?

Choseras crack because when you soak them they swell a little, next when you dry them too fast the outside will dry faster than the inside causing stresses in the stone.
What really helps is if after use you dry them with a microfiber cloth and use that slightly moist cloth to wrap the stone.
This way the stone will dry slowly and evenly trough out preventing cracks.
I had some hairline cracks in mine before I realized this and after lapping them out and using above method never saw any cracks again.
