The technique can date materials the size of one grain of volcanic ash, using a laser.There are other methods which can be used as well which operate using different radiochemistries.Volcanic rock -- like the trail at Laetoli -- can be dated by a method called potassium-argon dating.Hot, newly erupted lava and ash contain a form of the chemical element potassium (called potassium-40) that is radioactive.Can you find the age of rocks by using radiocarbon dating or are they generally too old?If a rock was shot from a volcano and isn't that old, can we use radiocarbon dating?There is a number of different techniques available.

This means scientists can date rock which is many millions of years old."Absolute" dating means finding a specific age for an object.A sample of volcanic ash, for instance, can be given an absolute date of 3.18 million years old.25 volcanic ash may be used on a compost bin filled with supercompost for 15 buckets of ultracompost essentially saving 5 ashes per bin (volcanic ash can be used right after a compost potion) alternatively two ashes may be used on a bucket of supercompost to create an ultracompost.If players have read the ash covered tome, they can have the Fertile Soil spell treat a farming patch with ultracompost instead of supercompost by casting the spell while having two volcanic ash in their inventory.
