  1. I am shopping for a new (or, at-least new to me) kiln. My JW Good manual kiln was severely damaged when a large walnut tree fell on my garage. On the plus side, I get a new garage - and a new kiln. On the down side, it will probably be at-last 3 months before the new garage is finished and I can fire anything. I'm considering a brand-new kiln, as I'm finding it hard to find decent used ones that are offered at prices far enough below the new to make it worth buying used. I'm looking for a relatively small ^8-^10-rated kiln, that I plan to fire at ^6. Something in the 3 cu.ft. range - such as the Skutt KM-822. It looks like the 3" brick isn't much more expensive than 2-1/2" ($75 more on the Skutt), so not really a big factor cost-wise - but I do wonder how long it would take to recover that $75 in reduced electricity cost - when I'm currently only firing 4-5x/year. I saw a recent comment from @neilestrick in another thread, that says in part "Thinner brick use slightly more electricity, but they cool faster.... L&L's most powerful kilns, the JH crystalline series, are rated for cone 12, but are built with 2.5" brick. The thinner brick allow for faster cooling times, and more precise temperature control." - which sounds as though the 2.5" may actually be better (or maybe it's just a non-issue with the volume I fire). The other aspect of the brick thickness I'm looking at is interior dimensions: Not so much in terms of capacity - but with regard to 'open space'. Does the amount of space between edge of shelf and brick have any effect on firing ? Assuming I'm using a 15" shelf, centered in the kiln, we're talking about 1.5" all around vs 1". The extra 1/2 inch of finger space between shelf and brick when loading/unloading might be nice - but would it possibly make any difference in even distribution of heat within the kiln ?
