I really do not know what type or size this is all I can tell you is it's a very big kiln, about 50 molds, cones, paints, glazes, shelves, and even some clay. I got this a couple of years ago, never used it. The top is broken but did find out it can be fixed. Any crafter that would like to start making there own pottery collection, this would be great... Pleasecall Eric or Shelly 3304727496 leave a message, we'll call you back. I'm firm on this price! Thanks
