  1. Your stories about the 'air bubble in the veins' thing reminded me of when I worked in seismic oil search in the late 70s. The vibrator trucks (used to send sound waves into the earth) ran an extremely high PSI hydraulic system and we were always warned never to put our hands anywhere near the hydraulic lines when they were running. Tales were told of mechanics that received blood poisoning from pinhole leaks that forced oil under the skin as they were running their hand along the hoses. I'm unsure if the tales were true, but I erred on the side of caution.

  2. Magnesite has a Mohs of around 3.5. However, when processed into refractory bricks, I believe it becomes much harder. I wonder how it would survive?
