Pyroclastic rocks are the product of explosive volcanism. They are often felsic (high in silica). Pyroclastic rocks are often the result of volcanic debris, such as ash, bombs and tephra, and other volcanic ejecta.henocrysts are crystals that are larger than the matrix and are identifiable with the unaided eye. Rhomb porphyry is an example with large rhomb shaped phenocrysts embedded in a very fine grained matrix. Volcanic rocks often have a vesicular texture caused by voids left by volatiles trapped in the molten lava.

Store quail eggs with the small end facing down. Try to keep the quail eggs at the correct humidity prior to incubation which is a humidity of 84-88%.Make sure the stored quail eggs are turned twice daily before they are incubated. Keep the stored quail eggs in an egg carton and prop up one end at a 35 degree angle.
