When it comes to mineral and rock identification, the streak test is the best! Black Streak Plate is an unglazed ceramic tile that lets you identify specific minerals by scraping them across the surface to reveal the characteristic colors. Black porcelain plate is best to use with white or lighter minerals. Each streak plate measures 1 L x 2 x 1/5 D inches. Sold as 10 per pack.
  • Classroom-friendly streak plates are the easiest, most visible way to identify rocks and minerals by testing out/rubbing streak color across the surface
  • Color of marks left behind are retained, vivid, and easy to see across the porcelain tile
  • The line marks left from streaking also reveal hardness or softness of mineral, rock, or fossil for even more identification clues
  • Set of 10 budget-friendly black streak plates are a must-have for middle to high school earth science and geology classes
