Day Seventy One

We took photos of the grains of metallurgy copper. It's actually a lot cooler than it sounds. =) We took this powder, and pressed it into a mold under 29K pounds of pressure. We made two samples. We cooked one at 867 degrees and then Squished them both. The uncooked one cracked and crushed back into powder at 30K pounds of pressure. The machines we have only go to 60K pounds of pressure and the baked sample handled all that stress with no problem. =)
