Fellow Clay workers - I just returned frm a week long warm glass class and
I'd like to fuse and slump glass in my electric Blue Diamond, bar cone
using kiln. The kiln currently functions with three knobs , one for each
of the collars, that have the Low-medium-high settings, which I use to
fire my pottery in stages.
I know I'll have to plug up the ports in the side as well as the one on
the lid to prevent thermal shock, but is there anyone who can advise me
further?

I would start experimenting by firing small glass test pieces on several
evenly spaced shelves. If the temperature is uneven, then fire more slowly.
Once you are comfortable with the process, begin firing actual glass
projects.
Position the shelves so that you can see the glass through the peepholes.
This is important, because you will know when to turn off the kiln by
watching the glass. It is the same idea as watching cones on a shelf except
that the glass is easier to see than cones. The glass fires to only around
1450 degrees F where the kiln interior is orange instead of the bright
yellow of ceramics.
The glass will go through many stages of fusing. At first the glass will
turn orange, and then the edges will just begin to round. The layers will
sag and then fuse more deeply. When the glass reaches the stage of fusing
that you like, turn off the kiln and let it cool to room temperature.
