I put together a couple videos that discuss total organic material testing.
First, this one, which shows some samples I’ve collected. From my office, to the post office, I discuss what is going to happen with them at the laboratory.

This looks at the green itself, moves on to drying the samples, to what the samples look like after the burn in the muffle furnace. Let’s just say the organic matter is turned to ash.
More information about the sampling and the mass loss on ignition are explained in:
