- 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. This set of twelve samples is excellent for group study and examination
- Each specimen is selected and hand processed, ensuring each sample exhibits defining features
- Sourced from a variety of locations around the world
- Each specimen sample is packaged in a transparent bag, and is labeled & barcoded for easy identification
