Blob. This is a big blob of beryllium from China, part of a one-kilogram lot Max purchased for making element samples for his commercial sets and museum displays. It's very light for its size, so much so that it seems hollow, but he's broken some of these open and they are not. The white granular stuff hidden in the crevice is a bit alarming: If it's beryllium oxide then it's dangerously toxic: Until this has been determined I am keeping this sample in a sealed bag and handling it only gently and with gloves.
