United Scientific™ Glass Streak Plates for Mineral Testing, 3x2", 10-Pack
Product Information
About
MINERAL HARDNESS TESTING: Glass streak plates designed for hardness testing of rocks and minerals in geology classrooms, field work, and rockhounding kits.
DURABLE FLOAT GLASS: Quarter-inch thick clear float glass provides a flat, consistent testing surface that withstands repeated scratch tests across multiple minerals.
VERSATILE LAB USE: Beyond mineralogy, these plates work as flat work surfaces for glass etching projects, laboratory crafts, and educational demonstrations.
PROFESSIONAL DIMENSIONS: Each plate measures 3 inches by 2 inches with 1/4 inch thickness, sized for handheld use during field testing and classroom demonstrations.
BULK PACK OF 10: Ideal for geology classrooms, teaching labs, rockhounding clubs, and educators needing multiple reference plates.
Product Description
These glass streak plates provide a flat, durable surface for mineral hardness testing in geology classrooms, field work, and rockhounding kits. Each plate measures 3"" x 2"" with 1/4 inch thickness, giving you a stable non-porous surface that withstands repeated scratch testing.Float glass construction provides a consistent flat surface for accurate mineral hardness testing across multiple samplesQuarter-inch thickness gives the plates enough mass to stay flat during handheld scratch testing in the field or classroomPack of 10 plates supports geology classrooms, teaching labs, and rockhounding clubs needing multiple reference surfacesFlat glass surface also works for laboratory crafts, glass etching projects, and educational demonstrationsCompact 3 inch by 2 inch dimensions are sized for handheld use and easy storage between testing sessionsDesigned primarily for use alongside ceramic streak plates and other mineral identification tools in geology kits. The flat, uniform surface gives a reliable comparison reference when testing rock and mineral specimens.Suitable for educators teaching earth science, geology students, rockhounding enthusiasts, and laboratory professionals who need standard glass plates for testing and demonstration work.
