EISCO Scoria Specimen (Igneous Rock), Approx. 1" (3cm) - Pack of 12
Brand: EISCO
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. Scoria is a good example of pyroclastic material, and can be used to great effect in igneous classification exercises.
