A friend and I were discussing stacking the ware in the kiln to save
shelf space. (Stacking: placing one piece of greenware inside another.)
He has heard that it is not advisable, because the ware doesn't receive
as much venting. What is your opinion?
Is there a trick to stacking ware successfully without breakage?
Thanks,

If you slow down the firing for the last 1 hr to 1 1/2 hrs ( about 80 deg
F/hr ramp) you will get the proper firing results.

I did much of the firing as an undergrad and worked as the student firing
assistant to the staff tech at a large art institute for a bit.
Just so you know, I have stacked many a bisque electric kiln in addition to
many gas bisque firings when classes had an abundance of work.
I have found breakage to be minimal to non-existent for normal cups, mugs,
etc. Just don't get crazy with how many you stack. I've had more problems
with some warpage of larger platters but generally haven't stacked plates
more than three deep and kept stacked ware to items of the same size.
If the ware is dry, venting isn't that much of an issue.
Of course, if the ware isn't well thrown and rims aren't compressed, etc.
you probably will experience more problems at points where ware is
supported.

What works for me....I cut 2" round biscuits when I am slabbing
ware(actually I get my husband to make these,as he does most of the slabbed
work here)...I place 3 of these evenly placed between plates, etc...and
seems to work well..I think they receive the proper venting and I haven't
lost any plates or platters when bisqueing since I started doing this, I
stack 3 or 4 high...and the added benefit of having all these round pieces
around is that, I don"t kiln wash and use them under pots when glazing..

I stack rim to rim, and foot to foot. Fire slowly (listen to Ron Roy!) and
to date (knock wood) no problems.
The ONLY time I had a problem (pre RR ;-) with stacked bisque was when I was
in a hurry, and you could clearly see different colours where the pots were
touching. So much for saving time - had to re-bisque the whole dern thing
slowly.
