TITANITE Pike Quarry, Hooksett, NH ~ 0.45 mm crystal TITANITE Pike Quarry, Hooksett, NH 0.34 mm crystal	Species: TITANITE Locality: Pike Quarry, Hooksett, NH Specimen Size: ~ 0.45 mm crystal Field Collected: Bob Wilken Catalog No.: An Anna Wilken specimen. Bob WIlken photo Notes: [bw] In the course of retaking the Pike Hooksett titanite photo I decided to do a comparison of how different the result can be depending on whether I put the specimen inside the ping pong ball or if I put the ping pong balls over the LED lights. You can see how the first way dulls luster and prevents light from penetrating the crystals. The second way you really see the crystals more like the eye sees them through the scope. But, often there is the tendency for the latter method to end up with flaring. It didn't in this case although the two little stripes on the end of the narrow crystal are quite bright. With masses of numerous reflective crystals, the ball over the specimen is the best way to go but at a sacrifice.
