I have been reading up on some of the experiences other have had in making
cones. I have used this experiment to help learn some glaze software and as
a fun thing to try.
I am following the Harry Davis book and have a couple of recipies derived
from the seger formula for cone 6. I am having trouble in the forming stage.
When I try to remove the cone from the greased mold the tips always break off.
Is there some kind of binder that I can add to the mix to make the cones
more durable in their dried state?
Thanks,
Ben

Ben, I have made my own cones and found some of them
to be very fragile.
I could usually make them more durable by using ball clay
rather than kaolin in the recipe. Of course, this will significantly
alter the formula, and a completely new recipe must be
calculated from the Segar formula.
I also bisque fire the cones, to make them more durable.
I have not done this, but I think you could add an organic binder
to the recipe. Corn syrup of Elmer's glue might work.

corn starch, the stuff you cook with, sets up very
hard if you mix it with water and then let it set.
Also, egg whites. They will set so hard you would
have a very hard time getting them out or off of
anything. And if you whisk them lightly, they have a
perfect consistency. People used to paint with it.
(eventually fell off the wall, but it took 400 years
or so.)
Maybe you could mix some into your clay. It also
should fire completely out.
