6PK Raw Pumice Igneous Rock Specimens - Approx_ 1 - Geologist Selected and Hand Processed - Great for Science Classrooms - Class Pack - Eisco Labs

Raw Pumice Specimen Set of 6 Samples, 1" Pumice is formed from the frothy lava that a volcanic explosion creates. As the frothy lava cools, it hardens as a light weight rock that is filled with small gas bubbles. Because this rock is so porous and light, it can actually float on water. Perfect for demonstrating the effect of vesicles on rock density, as well as for lesson in identification and classification of igneous rocks. While each specimen will vary slightly in shape, size and color, it will measure approximately 1" in length. Each is individually packaged, labeled & barcoded for easy identification and storage. Selected & Processed by a Geologist. Each and every specimen is selected and hand processed by an actual geologist, ensuring that each sample exhibits defining features. Rocks and minerals are sourced from a variety of locations around the world and are processed by hand in Victor, NY.
