United Scientific Glass Streak Plates - 3x2 Inch Mineral Testing Plates (Pack Of 10)

Every geology lab needs reliable streak plates for mineral identification, and this United Scientific 10-pack delivers consistent performance test after test.

Each plate measures 3 inches tall by 2 inches wide with a 1/4 inch thickness that stands up to regular use without breaking.

The smooth glass surface provides the perfect medium for performing streak tests to help identify minerals based on the color of powder they leave behind.

Simply rub a mineral across the plate and observe the streak color - a fundamental technique in mineralogy that's more reliable than visual color identification alone.

Made in the USA with consistent quality, these plates are essential for classroom demonstrations, field geology kits, or professional laboratory analysis.

The pack of 10 means you have plenty for group activities or replacements when plates become worn.

They store compactly and clean up easily with water for reuse.

Whether you're teaching earth science, conducting field research, or just curious about rock identification, these professional streak plates are a fundamental tool for any mineral testing toolkit.
