As Rebecca said, she, as well as many others, use ceramic kilns for glass and it is different from learning with a glass kiln. A glass kiln also has top elements while a ceramic only has side elements so if you ever want to switch over to a glass kiln you'll be learning to write schedules all over again! Not a major thing but kind of like starting from scratch!
I personally wouldn't want a kiln without a digi controller.
Not quite from scratch! All kilns are different and even a new glass kiln will take a little practice to get a handle on those differences. I have a glass kiln and use it also. It is smaller than the ceramics kiln, so I use the larger one more often. The glass kiln has elements in the lid only and the ceramics kiln has elements in the sides only, but there is not much difference in the programs I use for them.
