This will be a glaze firing we at cal-earth have a fair amount of =
furniture [ shelves and posts] but not enough to carry out such a =
large firing. The volume of this beast is 677 cubic feet. I =
got this by the volume of a hemisphere on top of a cylinder two feet =
high and both with a radius of six feet 1.33xPIx6^3/2 + 2xPIx6^2 =
=3D 677^3ft
=20
So as time goes on and we can see more clearly the pots and sculpture =
available we will able to work out the logistics of this event. My plan =
is to finish the dome and soccer ball by the first of january and then =
load the kiln in the first and second week of the new year
and then begin firing on the 15th i plan for two days of climbing and =
two days of cooling before cracking. We are using propane and =
targeting o6 for the final temperature with a mild reduction so glazes =
formulas should be aimed at this sort of firing. =20
I hope this answers some of your questions and that you might like to =
join in the event in January or at any other time in the process.

I see.. that would certainly reduce the surprise factor.
I some how envisioned a weekend drop in scenario.(crazy)
>>This will be a glaze firing we at cal-earth have a fair amount of

firing<<
I'm thinking how some kind of simple, inexpensive, makeshift
furniture may assist your stacking and reduce breakage/welding.
Paper clay panels/stilts with bat wash?
Minor blemishes here and there are fine...
have seen sea shells commonly used as supports with good effect.
I mean pots are more easily handled but
I'm thinking some of the more fragile
sculptures may pose problems.(any ideas out there, clayart?)
>>and that you might like to join in the event in January or at any other

Thanks for the invite..
will be an exciting event I'm sure.
As I am residing on the otherside of the planet (India)
this could pose as a possible inconvenience. ; )
May your venture be
more successful than you can imagine.
