Heat cracks onyx!

I spent all day digging out the interior of the sculpture and discovered that the stone will expand and crack if allowed to get too hot. Luckily the area damaged was small and i was able to cut the damage away. Onyx seems to be much more sensitive to heat than marble. The sun shone all day although it was too dark to continue at 5pm.
