Potassium-argon (K-Ar) dating technique is the most appropriate dating method for establishing the age of a volcanic ash.

Since potassium is a common element found in many volcanic ash layer, the time since re-crystallization is calculated by measuring the ratio of the amount of argon 40 (Ar-40) accumulated to the amount of potassium 40 (K-40) remaining in these volcanic ashes.
