Jason -
I've just resumed throwing with an English grolleg porcelain (^10), after
many years of badmouthing it! Never thought I threw particularly fast, but
I find if I slow down, and have a propane torch handy, it works fairly well.
Also, John Rodgers suggestion of using a porcelain slurry to throw with
instead of water is definitely the way to go.
Take your time, and enjoy the ride!

Subject: grolleg porcelain
is it just me or does grolleg porcelain absolutely suck to throw with?? i
used to think i was a pretty darn good thrower untill the past 2 days. i've
turned out some amazingly beautiful and large pots using my ^5 stoneware. so
when my art teacher and i were ordering new clay in mass i suggested the ^5
i was using and a few hundred lbs of its brown cousin. and to boot we threw
in 100 lbs of grolleg porcelain just to test because i know at ^10 and such
it turns translucent when very thin and works great in slab work. and i
usually have no problem making very thin pots...so i wanted to make some
pots that were translucent.
ive struggled and used every little trick i know to eek out a bowl thats
about 4 inches tall and 8 inches around. i was successful after about 8
failures....it's been ridiculous! and i know people throw with porcelain all
the time...but thats the normal porcelain...not the grolleg. so am i really
that bad of a potter or is grolleg just one of those bodies definately not
intended for throwing.
very frustrated and annoyed right now.

Jason, you are probably going to get all kinds of responses on this.
My experience - Standard Grolleg- Cone 6
Grolleg to me is the finest of the porcelains you see out there. And it
is touchy. It requires much less water than other clays, even other
porelains. In throwing Grolleg I find it imperative that I make a
porcelain clay slurry to throw with, rather than use water. I also find
that I cannot rush with Grolleg. The kind of handling required for
Grolleg is best said in a quote from the Rubiaat of Ohma Kaa'yam, as
the potter prepares the clay for forming, says the clay to the potter -
'Gently, Brother, gently!"
I work grolleg with the slurry on one side of me, and a hot air gun at
my right hand. The hot air gun is used to stiffen the clay at points
where needed, otherwise a collapse would ensue.
Give it a go. It worked for me.

Hello all,
To avoid confusion can someone clear up what is meant here by Grolleg
porcelain? The reason being that Grolleg is a trademarked name for a grade
of English kaolin, which on its own wouldnt make porcelain. It of course
could be used in a formulation but I doubt if the owners would be happy for
another company to use that name for another product

Antony

It is straight forward: Grolleg porcelain, which is available at many
clay companies in America, is a porcelain body made with Grolleg kaolin,
which is imported from England. Grolleg kaolin is Grolleg kaolin.
Maybe you don't have access to Grolleg porcelain where you live?

Thanks for the clarification Lee. I know Grolleg kaolin well but I was a
little puzzled about =91Grolleg Porcelain=92 as opposed to =91Porcelain prep=
ared
with Grolleg kaolin=92. Sure the former is a more snappy name but I was
pondering the legal implications of using a trademark in such a way
