Eisco - Raw Coarse Marble Metamorphic Rock Specimen 3" Hand Sample Labeled for Geology Classroom Identification and Acid Reaction Demonstration

The Eisco Raw Coarse Marble specimen is a 3-inch hand sample of metamorphic rock ideal for classroom study and hands-on learning. Formed from limestone under high pressure and low heat, marble has a massive crystalline texture that helps illustrate the effects of metamorphism in geology lessons.This specimen is excellent for identification activities, as it retains the ability to effervesce in dilute acid, distinguishing it from non-carbonate rocks. Each piece is individually labeled and barcoded, and comes packaged in a clear storage bag. Hand-processed in Victor, NY, this sample supports NGSS-aligned instruction on rock transformation and mineral properties.

• IDEAL FOR GEOLOGY EDUCATION || Great for lessons on metamorphism, mineral structure, and rock cycle transformation from limestone to marble.
• ACID REACTION DEMONSTRATION || Despite its dense crystalline structure, marble will effervesce in acid, making it useful for classroom identification labs.
• LARGE HAND SAMPLE SIZE || Measures approximately 3 inches, offering a substantial surface for observation and handling.
• LABELED & PACKAGED || Individually labeled and barcoded, each sample comes in a clear bag for organized classroom storage.
• LOCALLY PROCESSED || Rock is sourced globally and hand-processed in Victor, NY, ensuring quality and consistency in education settings.
