- Scoria forms as spatter from bubbly, mafic lava is thrown into the air and cooled quickly. The crystallization happens so quickly that large air pockets are trapped within the rock, often giving samples a jagged, sharp appearance
- A good example of pyroclastic material. Can be used in a variety of igneous classification exercises. 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
