As many here use electric kilns and may not be aware of what is possible as far as stacking your work-whether its sculpture or pots.
You do not have to place them with space between or even on the feet- pack it tight. One can fill every nook by placing pottery in any direction.
I only bisque fire in my electrics and rarely at best these days,as the gas kilns are larger and cheaper for me to run. That said when I need a little last minute work I’ll fire one up in the evening as that’s the best electric rate with my (TOU) Time Of Use electric meter. If you fire your electric kiln a lot you may want to check with your utility on this meter as you are charged different rates at peak times and lesser rates off peak. The meter does have a daily charge to own. Ours paid for its self in a few months as we try to only use power on things like cloths washing-dryers (motors) and electric kiln use off-peak hours.
I use kiln shelves as usual during the loading but stackpots in all directions per layer to get the most use of space. Whatever you can squeeze in-filling the insides of pots, pots on the edge or upside down or sideways-no matter
The key thing is that the work is bone dry. Now this may not work on a sculpture you have worked on for 3 months and is still wet in the center.
So the next bisque fire try to fill all the space withtumble stacking in mind.
