Thank you for the input Nils. My plan at this point is to go ahead
and try a full speed bisque and a full speed cone 10. I will probably
get to the bisque on Thursday and the cone 10 on Saturday if all goes
well.
Regards,
Heather Pedersen

Heather asked about how fast could she fire her thin porcelain
slabs.=3D20
I usually respond to these questions suggesting that you try it out with
a waster sample. But, it is quite likely that you can fire them to temp.
at the same starting rate, 400 F /hour, No need to switch to a slower
temp. If they are DRY to start you can fire as fast as the kiln can go. =3D
Initial drying
can be enhanced with a hair dryer or if they are small enough, just =3D
micro
wave them for 60 seconds on high.=3D20
It's a similar question concerning firing anything already bisqued. Time =
=3D
and fuel wasted
on candling is just that. Turn the kiln on full and go. Once firing is =3D
another story because
of the water of plasticity, and the chemically bonded water needs some =3D
time to escape.
For heather, though, the thin slabs can probably take a full on go.=3D20
