Streak Plate (Educator's 10-Pack)
This is a 10-pack of our unglazed ceramic tiles, used for the streak test and hardness tests for minerals. Our generously sized 2"x2" tiles come in your choice of white (for most minerals) or black (helpful for light-colored minerals) Cleans easily with soap and water for years of use.
Classical Conversations Directors: this is exactly the type of streak plate you need for 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.
