Tom,

The diatomite Joe DiDomenico sent me was very smooth, and the dust on the
surface gave it almost a talc-like feel.

Remember that diatomite is crushed, calcined muds of fresh-water diatoms,
not the washed shells of marine diatoms we see for filtration or
horticultural use.


That would explain it. Do you like it as part or all of a growing medium?
