I rolled a variety of leaves, flowers, weeds, etc. into clay and bisqued
them. This was an attempt to make some pressed appliques to apply onto pots
with slip. (I know, appliques is the wrong term, but I can't think of the
correct one.)
Anyway, I notice there is a powdery, kind of fluffy, residue left after
firing. I suppose it can't be organic material as that should have all
burned out. I am just wondering what it is. Would it just be powdery clay?

Marianne,
I suspect that would be ash. Grasses, especially, contain a good bit of
silica as well as other things which don't burn out.

I believe what you have is ash from the leaves.
It is interesting to leave it in place and glaze over it. (A little hard
to do but fun nonetheless)

My guess is that it is a salt residue. This should melt at a higher
temperature, and perhaps have a more pleasant effect.

Marienne, it is the residue of whatever was there before, paper, whatever.
It stays, burnt in place, in an electric kiln because there is no draught to
move the ashes. Sometimes it can look a bit spooky.
