I have spent the entire day searching online as well
as the clay art archieves for some information about
pit firing.

In my back yard, I have a cinder block fire pit. I
would like to use it for pit firing s few things to
see what happens. Anything I could find any where
pertained to huge dug out pits, barbeque's, and metal
drums. Of course I also found how to do a pit firing
type technique in an electric kiln.

Now from what I read about all the other methods, it
appeared that I should dig into the earth a couple to
a few feet. I thought of digging down about 2 feet
below the cinder blocks to be able to put my saw dust,
other goodies and my pottery below ground. The cement
blocks that go around the actual pit are about 30
inches high, and 30 inches 9inside lip to inside
lip)wide across. I am going to get a few more blocks
to expand that circle out for a little more space. I
would like it to be about four feet around, inside lip
to inside lip.

I am wondering how to get air into the bottom of the
structure. I read that for the metal barrels, you need
to cut holes into the bottom for air circulation. How
do I do this with cement blocks. Do I space them apart
an inch or two, instead of placing them tight together
like I normally would? The there is the issue of
having a cross draft. Is it of dire importance for a
small round fire pit?

I honestly did a search but nothing I could find is
directly related to what I wanted to do. I don't want
to inconvenience everyone by asking them to type long
instructions. Does anyone have any links, or has done
this themselves. I was pretty surprised that I could
not find anything in regards to a cinder clock fire
pit. I wish I had the property to dig a huge trench,
but a fire pit is the best I can do.

I am going to try this no matter what, unless it is
hazardous to one's health. I just want it to work out
the best way possible. I am not near to being ready to
try this, but while it is nice out here in Canada, I'd
like to prepare the fire pit.

thanks for any info anyone might have on this.

It seems like you have a plan and well on the way to making it work. The
only thing I can tell you from reading your posting is related to air to
make your pit burn, in the pic here
http://www.users.bigpond.com/sdkelly9/pottery/pitfire/pages/pics-14.htm
there is no holes, trenches or anything to get air to the bottom of the
pit, if the top is relative to the depth there should be no problem and
will allow a full and slow burn.
