Richard Gralnik and Bruce Girrell were discussing slumping glass.
I have been troubled at night by insomniac visions of translucent porcelain
slumped into molds, maybe with carvings to heighten translucency, possibly
slumped into shapes that can be put together into sculptural or other
composite forms. I'm thinking take a tile, carve what you will almost
through it, put it in a fireclay form and fire away.
The problem is this is seems like an entire PhD thesis amount of work and I
am saving my PhD energies for comparative lit someday. Any recommended
references to check out if I want to undertake this? How about (quitcher
snickering, now) at cone 6?
tossing and turning...

Hello Jeff:
Have you seen Benzle's work? They have done some ultra translucent stuff at
cone 5 I believe. Yes, it's possible and not that tough to do at cone 6. A
friend of mine did some translucent porcelain stuff at cone 6 that wasn't as
"light revealing" as Benzle's stuff but still worked. He wasn't trying for
translucency but fluxed the body enough that he was given a gift.
If I were doing this, I'd use Grolleg as it is one of the most translucent
china clays available. Try blending potash and maybe another series with
soda spar until you get what you want. Then, if you want a reasonable glaze
fit, you'll need to blend in some silica.

Hi Craig,
Hope you don't mind my butting in here with a question. If one is
firing Grolleg porcelain at Cone 6, won't the clay remain unvitrified and
wouldn't lack strength. Please forgive me if this is a stupid question, but
I really would like to try throwing almost translucent pieces and only have
access to Cone 6. I would not feel comfortable with selling pieces if they
lacked strength.
Thanks in advance for your help, patience, and forbearance!
All the best.

Hi Jeff.
I've been running ~ 700 messages behind, lately, but the
slump idea sounds fun. To make the thin cut outs why not
try a sandwich? One tile cut all the way through, and a thin
slab slip-bonded to it. I do similar things with my tiles at
cone 6 with good results. Saves the *careful* carving and
works with cookie cutters, etc.
