  • Large crystals in variety of shapes and colors
  • Felsic plutonic rock ideal for lessons in mineral identification and bulk rock chemistry
  • For comparing cooling rates between samples with differently-sized crystals
  • Correlates well to Next Generation Science Standards Evidence Statements
