The mantle makes up most of the Earth’s total volume, but it has never been physically explored. This mysterious hot layer reaches temperatures as high as 3700C (6692F). Geologists believe that diamonds are formed in the mantle Continue reading “Inside the mantle”

It is a moment of tension because you can easily break the glass sculpture trying to apply force to separate both surfaces.

This grinding/polishing disc is around 40kg (88 pounds). I have to clean it extremely well every time I switch from one grit stage to the next, as any previous grit left on the disc can cause scratches — one of the most feared moments because it means you have to start over and spend several days polishing again to get rid of that scratch.
