  4. Yes, It HAS been confirmed. there are a type of meteorites that are called Chondrites, and they are made up of chondrules. They tell us that there is proof of the big bang (you need to read about them to know why)... I recommend the book "Rocks From Space" by O. Richard Norton. We can also track back to the time of the extinction of dinosaurs by looking at Iridium in KT boundry clay.
  5. Only corrode the kamacite, if the others corrode, ill run the windmanstatten pattern
