I have used several large scoops (I am mentioning volume because it is
so light) in 100-150 pound batches. I have used it in raku clau only. I
threw with it.
Mixed it in a Soldner mixer.

Oh it is defanately an adventure !! : ) May I suggest
wetting the vermiculite before mixing ... And then
after wedging it in let it set at least overnight and
wedge again... About the amount .... Well how much
salt do you put in soup... It is all a matter of
prefrence and need...
Good luck and have fun.. tehehehe.. Careful
trimming....

I have had trouble accessing the Archives today. Can anyone tell me how to
use vermiculite in a claybody? Do you mix in right into the clay? What are
the proportions. Isn't it hard to throw with all the chunks in? Any
details would be helpful. Thanks

Dear Llewellyn,
A long time ago there was an article in CM about vermiculite in clay.
You just wedge a bit into your clay. However I found that the vermiculite
burned out or disintegrated in some way and resulted in a surface that was
cratered and not smooth. Nothing for a functional ware I decided. For
sculptural purposes that would be another matter. I experimented with
vermiculite quite some time ago, (there are also different sizes of
vermiculite, some are coarser than others) and have to dredge my memory as
to the result. All I remember was that it was not anything I wished to
pursue. Mia in ABQ

I have seen vermiculite sprinkled on the surface of a
platter, then low salt fired...the result was
a gold/irridescent sprinkle affect.
quite nice.
go lightly, use as highlights.

I have only seen it used in Earthenware Terracotta flower pots, fired
to cone 03. The vermiculite gives golden speckles on the terracotta
finish and looks so different then anything else I have seen. I do
not know how much the potter used but a lot of potters asked what the
gold specks were, The pot themselves had been made in a big round
mould so there was no turning involved,

Dear Marcia Slessor,
Perhaps Llewellyn Kouba should take a look in back issues of Ceramics =
Monthly for information about Perlite Bodies. Bill Hunt did a lot of =
research on this topic about 20 years ago.
I am sure that the information he derived from his research will help.
Best regards,
