Preventing Uneven Bowl Slumping
This is part three of a
multi-part tip on preventing uneven bowl slumping. Click here to go to part one.
A few more suggestions to help prevent uneven bowl
slumping:
7. The likelihood of an uneven slump can also be minimized
by careful choice of mold and fused blank. In general, uneven
slumping is less likely when the mold has a wide rim. Molds
with a narrow rim (or with no rim at all) are likely to slump
crookedly if the blank is balanced precariously on the rim.
Try to avoid that kind of setup, and your chances of an unevenly
slumped bowls will be lessened.
8. In some cases the blank to be slumped has a smaller
diameter than the mold and fits inside the mold. (This is
especially likely in a deep mold such as a wok.) In addition
to ensuring evenness by using a level, you can greatly increase the
chance of success in this kind of setup by lightly beveling the
edges of the blank. Just use a wet belt sander or similar tool
to bevel the underside of the blank so that it fits snugly into the
mold. This makes it much more likely to slump evenly.

fails and despite all your efforts you create an uneven bowl.
