Aside from cost and waste of fuel and pollution, what are the
disadvantages to firing to cone 10 reduction if I fill the kiln only half
full.....with lots of test tiles and cones dispersed throughout? If I get
the temperature up to say 1800 and reduce to cone 10 should i have
problems with celadons on porcelain?

Ed,
Shouldn't be a problem. I would recommend putting some
high-duty hard bricks throughout and using the usual number of
shelves to more closely match your typical thermal load,
slowing the rise and fall of temperature. You'd be surprised
how big an effect cooling time can have on some glazes.

go right ahead and fire em' you should have no problems as long as you
stack the kiln to an even density and fill the spaces with spare firebricks
and props. Usually the price of a couple of nice pots will more than cover
the cost of the firing

I would think it would fire uneven and be difficult to control, not get a good
reduction (being open space). Just wasteful energy on fuel and time.
