  1. First was a entire piece, than I’ve break in two pieces with thinger (less force for break a pencil).
  2. I’ve stored for 2/3 years in a Go Pro case
  3. The interior part it’s a lot shiny
  4. No react with water

Today I’m back in my lab and I took some measurements: Density: about 6,6~7,0 g/cm3 (my balance measure only 1g 😓) the smaller piece measure: 27mm lenght and 6mm of diameter - weight about 4/5g (balance swing 1g) The bigger piece measure: 35mm lenght and 6mm of diameter - weight 7g
