GLASS FUSING KILNS are designed to fire at temperatures up to 1700F degrees, these lower temps are suitable for most glass projects.
The elements in a glass kiln are placed in the lid of the kiln, as well as on the sides. The top elements work to radiate heat onto the face of the glass surface, while the side elements radiate heat throughout the kiln, stabilizing the internal temperature. Having top and side elements in a glass kiln keeps temperature differences within a glass project uniform and prevents cracking. Sometimes glass kilns are top firing only, and based on the size and materials in the kiln, that can be adequate for the heat demand. Finally, glass firing kilns always have a digital controller allowing for multiple ramp and hold segments for heating, cooling, and stabilizing temperatures throughout the firing process.
So how do you make your choice? What you really need to know is:
how much space you need,
what temperature do you need to go to and how long to hold...
and lastly, where can you plug it in? (How much juice do you have?)
Glass Fusers have specific needs that are different from other kiln users. Check out these links to help you make some crucial decisions.
