Well...... not really :) :) :) But it kinda looks like it could be....... This is actually a piece of ceramic material from a Cummins LNG engine's catalytic converter. The engine ran so hot it actually melted the ceramic element in the converter. This chunk is about 1.5 x 1.5 x 2 inches. I used a 90mm Tamron SP Adaptall macro lens, manual mode with my Nikon D7100, set the ISO at 400 and did 1 sec. exposures. I used f16 with the lens.
