Top-loading kilns have the advantage of being able to load your projects from above, allowing you to more easily center your glass-fusing projects on top of molds. In ceramic kilns and pottery kilns, you can fit more bisque firing ware and more layers into a top loading kiln, allowing you to produce more product in a smaller footprint.
Top-loading electric and gas kilns are economical and provide a huge value for buyers. When making a kiln buying decision on kiln configuration, always take into account the shape and size of your kiln shelf. The geometry of what can fit on your kiln shelf and how you load the kiln should always influence your decisions.
