Gordon -- I'm certainly no expert in this, but I know some people use a spray coating on their raku to preserve it's color and condition. IF the fixative in the spray is itself food safe, it seems to me that a good warning CARVED into the base of the bowl and a heavy spray of the coating would kill two birds* with one stone.

hello all, i have a lady that is determined that she must have a fruit bowl
like one that she saw in the shop and she wants a particular rake glaze that
we have. i tell her this is not food safe but she says it will be only for
fruit. there must be a danger still of the fruit being contaminated frow the
heavy metals becuase this is looking impossible.
first the shape she wants the raku clay i use will not support the walls so
i had no less than 4 pots collapse on the wheel, changed the shape and had 5
crack or split in two during firing.
the gods have spoken now i need your opinion,

Susan: You mention having the raku fruit bowls collapse on the wheel. Stop your work while it still has more clay to pull up. It needs to set up, dry somewhat to support the height and weight. If on a bat, you can take it off the wheel and work on something else or use a hair dryer, a torch etc., to hasten the drying. Also, check to see that you have left enough of a shoulder to support the height.
Several years ago, I had an order for some very large bowls---the lady called them bread rising bowls. After I had two collapse, I let the next dry for a while and then could finish pulling up.
Good luck!

Susan, at risk of aiding and abetting......(raku is for decorative
purposes only....raku is for decorative purposes only....raku is for
decorative purposes only).....what do you mean by a big bowl.
I regularly will throw bowls, which I often raku, that are from 14 to 22
inches in diameter. What has worked for me is to make sure that there is
enough clay to start with so that there will be a "buttress" of clay under
the wall (which will prevent collapse) of wide. shallow bowls. You will need
to play with it a bit to see what works best for you.You just trim the
excess clay away. If these are taller, wide bowls then you may have too much
clay up toward the rim and perhaps a thinner area somewhere in the wall.
Don't shoot for anything to thin to start.
One of the more difficult things for me was to learn how to successfully
fire them. Try and avoid grabbing the pot from just one side. This may
result in more cracked walls than you would like. I made a pair of tongs
with four curved tongs on the end that I can reach around the outside of the
pot, cradde them from underneath and then pick them up. This cut down on
loss considerably.
For much wider, parabolic type forms, I fire them on there side and
reach into toward the center of the piece with a standard pair of tongs.
This works quite well for me.
I use Lagunas WS4 clay body for the bigger pieces and make my own once
in awhile. THe mix is 100lbs Hawthorn Bond, 50lbs Gold Art, 50lbs Old Mine
#4. and upwards of 20 to 25% grog depending on how big and what types of
forms I have in mind. I also stated useing Kyanite at the suggest of Robert
Pipenburg who has been successfully using it for years. I used the 100 mesh
and the 45mesh in my last batch. The stuff seems to work exceptionally well.
Not as gritty as a 35mesh grog. Made the body to use for decorative platters
upwards of 3ft diameters. Haven't been able to fire any yet but will let you
know how well it works when I am able (gotta plumb in the new kiln first.)
Hope this helps
