Here is the corrected text: Raw Scoria Specimen - Single Sample, 1" Scoria forms when bubbly, mafic lava is thrown into the air and cools quickly, trapping large air pockets within the rock, often giving samples a jagged, sharp appearance. Excellent for classroom mineral study and identification, this specimen is a good example of pyroclastic material and can be used in various igneous classification exercises. While each specimen will vary slightly in shape, size, and color, it will measure approximately 1" in length. Each is individually packaged, labeled, and barcoded for easy identification and storage.
