    When using the “Kiln Drying” method, a sample is dried down to a constant weight by storing it in a warm, more dry environment. The term “Kiln Drying” has its origin, in a wider sense, in the drying (curing, preserving) of consumables. Aside from “Kiln Drying” there are other terms associated with this method such as “oven drying” or “oven drying method”. The higher temperature ensures that the
