Our white streak plates (2" x 2") can be used to test the hardness and color of rocks and minerals. They are reusable and can be cleaned with soap and water. 

Classical Conversations Directors: This is the type of streak plate you need for Cycle 1 Week 14's streak test experiment. It's flat on both sides so students can perform the test and streak-write their name on the other side!
