Yes, very dry and they sink in water, I think their density compares
with the ring die produced pellets.

I have "tested" a few,

I do not think they expand diametrically, they just separate into the
"wads" of sawdust in each ram stroke (about 10mm).

If used in an idd mode they would need primary air holes. I may give
it a try some time if I get enough round tuits.

Peter Verhaart built an idd stove, in Jakarta? with a jack to advance
the fuel, it may still be on the website.
