This white streak plate is a versatile tool for testing both the streak color and hardness of rocks and minerals. The light surface makes it especially useful for observing pale or lightly colored streaks that may be difficult to see on darker plates.
Each plate measures 2" x 2" and is designed for repeated use in geology activities and Earth science labs. The durable surface cleans easily with soap and water, allowing it to be reused again and again for years of mineral testing.
White streak plates are a helpful addition to mineral identification kits, rock collections, classrooms, and hands-on geology lessons, giving students a clear and simple way to compare streak results and practice proper testing techniques.
