Hi, I am the author of the theory being tested by the Brazilian work. Yes your comments about the balls being like liquid balls of molten metal are good ones, except that the observed balls are up to 40 mm in diameter, well above any molten metal balls anyone has seen. We think that these balls are much lighter, and the expected oxidation is spread throughout the ball, on small particles, in this case of silicon. John Abrahamson, NZ
