the Compact Wood Kiln Top Loader is the smallest version we offer. The ware chamber holds one stack of 12x24” shelves and is 30” from floor to lid; making it roughly 7 cu ft. Don’t be fooled into thinking this kiln is hard to load; the bottom 15 inches are comprised of the firebox and exit flue, so it looks deeper from the outside than it actually is. With a short 12-16” platform, this kiln is just as easy to load as most medium sized bisque kilns.
