TEPHRA AND PYROCLASTIC ROCKS. The rapid eruption of expanding gases results in the obliteration and fragmentation of magma and rock. The greater the explosivity, the greater the amount of fragmentation. Individual eruptive fragments are called pyroclasts (fire fragments).Tephra (Greek, for ash) is a generic term for any airborne pyroclastic accumulation.Whereas tephra is unconsolidated, a pyroclastic rock is produced from the consolidation of pyroclastic accumulations into a coherent rock type.he greater the explosivity, the greater the amount of fragmentation. Individual eruptive fragments are called pyroclasts (fire fragments). Tephra (Greek, for ash) is a generic term for any airborne pyroclastic accumulation.
Test the temperature of the milk with an instant-read thermometer once the milk has begun to steam and show small bubbles. Milk is considered to be scalded once it exceeds a temperature of 180 degrees F. Select a heat-proof measuring cup that is capable of holding at least twice as much milk as you wish to heat.
Prepare to feed the kittens. Sterilize the bottle and nipple in boiling water, then let them cool completely on a clean towel. Mix up the milk replacement formula using a little whisk to get the lumps out. You should warm the milk up to 95 - 100 degrees before feeding it to the kittens. As a final check, drip a few drops onto the underside of your wrist to make sure it's not too hot. Always make sure the kittens themselves are warm before feeding them. Never feed a kitten whose temperature is less than 95 degrees.
