I was wondering if anyone out there on the list who fires to cone 10
reduction would be willing to share they're average fuel costs per firing?
I know talking money can make people a little weird so you're welcome to
email me off the list if you like. If you would be willing to tell me
what fuel you use(natural gas/LP) the size of your kiln and length of
firing that would be great!!!
I'm trying to come up with a realistic range of firing costs to present to
my advanced students. It's one of those little tidbits of information
that I feel they should have an idea about before leaving school.
I've been firing with wood for the last 5 years and have no idea of the
costs of firing with natural gas or LP. We have gas kilns at the
university but no way to track the fuel usage to the individual kilns.
I appreciate your help!

?Your local gas supplier will be more than able to tell you the exact cost
of your firings. You will need to know the btu ratings of your burners, how
many inches of water column pressure you are using, the length of the
firing. Personally my kiln is approximately 9 cu ft. using 3 75000 btu
burners at 6 in of water column and fires to cone 10 in about 2 hrs. With
the cost of gas here in So CA each firing costs approximately $3

Hi Brandon
Firing my 25 cu. Ft. of stacking space IFB downdraft to ^6 reduction for
soda it costs me about $50 - $60 dollars. I fire with propane costing about
60 - 70 cents per Litre canadian. Thats about $2.50 - $3.00 per gallon.
Firing length is 8-9 hrs.

Hi Brandon,
I'm all propane. Here is a rundown on my kilns and what they suck out of th=
e
tank-
Kiln 1
Is a 45 C.F. Downdraft on propane, bisque is cone 04 in 6 hrs. 20 gallons o=
f
propane - Cone 6 in 7-8 hours 30 gallons, Cone 10 in 10-11 hrs, 40 gallons
of fuel
Kiln 2
A 100 C.F. Downdraft cart kiln on propane. Bisque fire is 6-7 hours 40
gallons of propane. Cone 10 in 12-14 hours 95-100 gallons of propane.
Kiln 3
A 18 C.F. Downdraft test kiln on propane. Bisque fire is 4 hours (hard to
control the early stages), on 5 gallons of propane, cone 10 in 6-7 hours on
10-12 gallons of propane.
Kiln 4
A 7 C.F. top hat barrel style Raku kiln - I've fired it to cone 10 in an
hour but pots were crap - a better schedule was 6 hrs with 4-5 gallons of
propane. This kiln would make an excellent first kiln that is easy to build
and very inexpensive compared to a brick kiln. Cost about $400 to build wit=
h
basic tools.
I hardly fire the 100cf kiln at all right now - the 45cf is a sweet firing
kiln that is a very predictable kiln - so much so that I'm reproducing it a=
t
my home studio right now.
I have found that the closer the kiln is to a cube - the more efficient it
is. My smaller test kiln is fired with burners that work very good at cone
10 but the burners are very hard to control in the early stages of a firing=
.
In a bigger kiln they would be fine. I started with smaller burners which
still had some low level problems but did not have enough power to reach
cone 10.
If any of your students are looking for burners, I'd recommend Mark Ward of
Ward Burners. I have found him a very, very knowledgeable expert who is
willing to help find the correct burner for the kiln size and type.
I hope this helps,
Larry Kruzan

I fire cone 10 redux in a 12 cf converted electric kiln.
I use propane.
My usual schedule is 2 hours of candling (I single-fire) and then about
10 hours to cone 10. That includes a 1 hour soak at 500 f and at 1800f.
I consistently use about 7 gallons of fuel start to finish, and figure
$30 per firing.
FWIW...
