    Isn't there some debate, over whether or not, the burnt off wax, effects the elements at all?


    Only if you want to start that debate.Posted Image

    Anything burning out in the kiln will affect the element life. But wax doesn't create enough carbon to matter.

    A 23x27 inch kiln with 3 inch brick will put out about 14,000 BTU's per hour of heat into the room at cone 6. That's like leaving two average size stove burners on full blast. At cone 04, about 11,000 BTU/Hr.


    True, but you have to also take into account the (supposed) air turnover rate in that space given the existing ventilation on the BTU / hr. accumuilation in the space? And also minus the heat pump efect of the AC unit in BTU/ hr.


    Agreed. Just wanted to give people an idea of how much heat comes off a kiln.

    Orrifice as given to me : .161 dia ( Via micrometer) According to chart (Ward) Approx. 181,000 btu.

    I'm assuming powered is more efficient but not sure if that works into formula.

    Not sure on kiln size yet, waiting to pick up more (free ) bricks, and furniture. Can we use 20 cu feet for discussion sake.

    Ill need 320,000 to 400,000 btu per hour. For hard brick kiln, 20 cubic feet

    Ward site states that power burners are designed to run on low pressures, 14"wc or 1/2 psi.

    Also ill be using propane.

    Neil, not sure what you're. Asking for when you mentioned pipe size.?


    The size of the pipe delivering the gas. My gas kiln used about 800,000 btu's. A standar household gas line, 3/4 inch pipe, can't deliver deliver a large enough volume of gas to keep up with that, so I put in a 2" line.

    14" WC, while low pressure, is double standard household pressure. If you plan on running natural gas, you'll have to have the pressure increased, which the gas company may or may not be willing to do at a home.

    If you need to put the kiln in a shed, make sure it is weather tight. If it has a wood floor, put down two layers of cement tile backer board under the kiln that extends about a foot beyond the kiln. You need about 18" clearance from all flammable materials, like the walls of the shed. A shed is a very small space for a kiln. You'll need good ventilation of both fumes and heat. That may mean leaving the door open on nice days, but with bad weather that means vent fans in the wall or roof. I could see it getting up to 150 degrees inside with the shed closed up without venting. If the circuit board on the kiln controller gets too hot, it will shut down.

    If you have any questions about L&L Kilns, feel free to contact me.


    I've got a question about L&L Kilns!!!!

    I was going to ask Jim, in another thread, as he is a fan of L&L, but I'll just ask here.

    Why do L&L Kilns tend to be so tall/ deep? I'm not a tall individual, and have to stand on the corner of the kiln stand, to place shelves and projects.

    At the first two districts I taught at, I used different Skutt models. I had to lean a little bit to load them, but could stay at ground level. Then I got to my current classroom, and there was an L&L, which I hadn't previously heard of. My first thought was, "Dang this thing is tall!"

    Don't get me wrong, it's a good kiln, and fires well. It's just a pain in the butt to load, at times, especially when I have larger, heavier, awkward shaped works.


    L&L kilns are the same dimensions as all other brands of kilns. 8 sided kilns are 17/18" wide, 10 sided kilns are 22/23" wide, 12 sided kilns are 27/28" wide. Each ring is 9" tall. It could be that the stand is a bit taller, or you've shrunk. The L&L stand is about 8" tall. Anyone got a Skutt they can measure?

    AND doing some hand building and needed the slab to harden a little and put it on some canvas on the floor and it dried just like that... this is a whole new wonderful space that I never thought about before!

    I just wedged my clay. I dumped the water off my reclaim, spread it on a big cloth and put it on my basement floor. Moved it a couple of times and it was perfect for wedging today and I want to thank you. It peeled off the material like magic. Thank you, thank you.

    I know you are very much politically correct and do not want to put any company that produces kilns down, but
    maybe you could give me an advice which kilns are the most reliable? I am interested in firing up to coin 6, middle size,
    electric, any voltage.
    Thank you in advance.

    NEIL;I made this small rimmed bowls out of porcelain, with the idea of putting a round candle in for Christmas.Before I waxed the foot, I brushed Alumina on, to avoid "plucking", as you suggested. No plucking, so thank-you for the suggestion.Tom Roberts

    Neil;I keep looking at that luscious yellow glaze on your teapot. Is your colourant rutile? Are you firing oxidation?Can we maybe trade a recipe or two?Tom Roberts[TJR]
