Photo of the day

Nickel sulfide inclusion - impurities - vents
At 200x magnification, more activity can be seen in the glass. The inclusion doesn't look spherical at all, but rather like a bird diving into water. The birdlike shape is a combination of the nickel sulfide inclusion, other impurities around it, and vents (small cracks) emanating from it.
