wadding to fire stacked glazed pots??

Ever fired pots inside one another??

I was wondering about the ratio of the wadding for in the wood kilns. What=
exactly do you use that crumbles away so easily?
I have a LARGE order of dog planters(20) and water bowls (60). (I have 40=
glazed with a gray shiny interior already)
I plan to fire a smaller piece inside each one to double up on the spa=
ce.(Just got this idea to save space)
I wondered if it were necessary to scrape off the glaze under the wad or l=
eave it and sand it later . It is not too hard to sand because these plan=
ters and dog water bowls are flat inside and the wad "scar" easy to get t=
o. The photo is of them stacked .
I thought If there were a little glaze left on =3D2C then after sanding i=
t =3D
might look pretty nice.--Although the raw clay would be okay too=3D2Cjust a=
ifferent color.
The tan bowls will hardly show the mark.
The blue design bowls are shiny so the wad mark would be highly visible.
These bowls take a LOT of kiln space with an empty "interior" so I really=
would like to double up.
Your Thoughts?

Thanks for the advice in advance.

Hi Amy,=3DA0
I have never done this; I just use plate setters for this sort of thing, bu=
t: =3DA0
I have great-grandma's bread bowl, which nicely demonstrates one solution t=
o stacking pots in a glaze firing. =3DA0The rim of the bowl is a bit thicke=
r =3D
than the walls, and has a sharp undercut to delineate the transition betwee=
n rim and wall. =3DA0(Think of the rim on a typical terra cotta flower pot.=
) =3D
=3DA0They were fired in a stack, the same way you would stack bowls in your=
itchen cabinets. =3DA0Because of the shape, the only place they touched was=
t the rim, so the potter just wiped the glaze off of the top of the rim, an=
d the undercut of the rim. =3DA0In this case the clay is the same color as =
e glaze, so most people probably wouldn't even notice. =3DA0It could also m=
e a nice accent to your rim if your glaze and clay are different colors. =
Thought number two, underglaze or colored slip can be your friend for this.=
=3DA0Make or buy a slip that matches your glaze and brush it on any area t=
t will need to remain unglazed in the firing stack. =3DA0Or do the whole po=
t =3D
in colored underglaze and then glaze with clear, leaving the necessary area=
s unglazed. =3DA0
Stuff a little wadding in the space between pots, or consider firing in a s=
aggar for these pieces. =3DA0Boring electric firers like me can just put th=

whole stack in the kiln. =3DA0
Off to pack pots!Maggie Furtak
