You can use common hard brick for your chimney. I have a 10 " diameter =3D
stainless steel chimney that I got from a=3D20
wood pulp factory that closed many years ago. I have built kilns for =3D
others and had them use a 10-12" galvanized culvert. The galvanized =3D
pipe works well and they are cheap. The bottom of the pipe, where it is =
=3D
sitting on the brick=3D20
base does burn off the galvanized coating, but that does not matter. =3D
Most farm supply suppliers will have the culverts=3D20
you could use. The chimney can be made vertically stable by using light =
=3D
cable to a solid structure or to several metal stakes in the ground. You =
=3D
can extend the chimney height by rolling a piece of galvanized metal =3D
light weight sheeting into the diameter of your chimney and pop riveting =
=3D
the end pieces together. I have cut some vertical slits in one end, =3D
folded the sections in slightly and some outside. Then the additional =3D
piece can se slipped over the existing pipe by putting some of the =3D
pieces inside and some on the outside of the chimney. It will stay in =3D
place that way or you can pop rivet the pieces together.=3D20
=3D20
Use the K23 brick on the inside layer of your stretcher course. Every =3D
4-5 courses of brick lay a header row of brick. This will hold the =3D
walls together.

I am building a new kiln now, so write if you would like some pictures. =3D
There some kiln pictures etc. on my Flickr site, which hasn't been =3D
updated in some time. =3D20

Subject: Kiln Question? Again...
Hello all I'm back and have a little dilemma. I recently found out I =3D
need to extend
my chimney and thanks in most to those on the forums I'm greatly =3D
appreciative. I
do have one more question though, I found bricks at a local store that =3D
are heat
resistant to 2000F which I think might do. I can order the K23 soft =3D
bricks for 3.70
each or I can get these local ones for a 1.50. The K23 bricks go to =3D
2300F. can I
use the local ones for the chimney? I already have 18" of chimney built =3D
with the
K23 but their so darn expensive. I'm firing to about 2200F max, do you =3D
guys and
gals think that the local bricks will suffice???
