porcelainsculptor Posted December 13, 2012 Report Share Posted December 13, 2012 Hi, need some expert advice please! So I am ready to get the kiln set up and I have two questions. I am having a cover built for it over a concrete pad - roof, no walls, and need to know how high it needs to be. This is the kiln, most likely it's Crucible: Also how big of a gas tank should I get for it? Will 150 gallons be enough? Or should I get 250? Thanks, this is my first kiln and I just want to make sure it is set up right! Link to comment Share on other sites More sharing options...
porcelainsculptor Posted December 13, 2012 Author Report Share Posted December 13, 2012 Well I went with a 150 gallon tank and eight foot roof! Hope that does the trick.... Link to comment Share on other sites More sharing options...
Rakuken Posted December 14, 2012 Report Share Posted December 14, 2012 Well I went with a 150 gallon tank and eight foot roof! Hope that does the trick.... My roof is corrugated metal. The height is 20 inches above the kiln with a fiber shield. When I fired with only one collar extension the distance from the top of the kiln to the roof was 30 inches without the fiber shield, I fired it that way for 8 years.

Do you think I need to get a fiber shield? Link to comment Share on other sites More sharing options...
Brian Reed Posted December 14, 2012 Report Share Posted December 14, 2012 I have the same kiln, although I have a small extender ring that makes it slighly larger. I fire it with two 100lb (25 gal) tanks plumbed in tandem and it works great. I build a hood out of galvanized steel to vent the heat instead. Make sure you put in a baffle shelf when you load it and know that the top shelf is going to be much cooler than the rest of the kiln. I fire ^10 reduction everytime now that I have it dialed in. Put two shelf pieces to block the vent hole as a damper with only about 2 inches open when you want to start reduction. Good luck. Link to comment Share on other sites More sharing options...

I am beginning to realize how little I know about this and it is making me a bit nervous - can you recommend a book maybe? Link to comment Share on other sites More sharing options...
Brian Reed Posted December 14, 2012 Report Share Posted December 14, 2012 Unfortunately I do not know of any books, nor have any books on how to learn to fire a gas kiln. I had some advice from people I know and the two page instructions from Seattle Pottery Supply. the rest was trial and error over a course of firing. Good luck and keep practicing.

justanassembler Posted December 14, 2012 Report Share Posted December 14, 2012 Nils Lou's book, The Art of Firing has some good information in it, if I recall correctly. Link to comment Share on other sites More sharing options...
