The beryllium oxide piece looks like a ceramic and can also be white. It is what he is hitting with a hammer @ 2:00 in the video
This is from Wikipedia:
"BeO is carcinogenic and may cause chronic beryllium disease. Once fired into solid form, it is safe to handle as long as it is not subjected to any machining that generates dust.[9] Beryllium oxide ceramic is not a hazardous waste under Federal law in the USA."
