Removing
Kiln Wash
from Glass
This is part three of a
three part tip on removing kiln wash from glass.

6. Sandblasting -- the easiest
solution of all. Sandblasting removes the
kiln wash completely and quickly. It generally takes about
a minute, maybe less, to gently and thoroughly remove kiln wash
from the bottom of a piece. The only potential downside is
that sandblasting does etch the surface, but even this cloud has
a silver lining -- once the piece is fired again (perhaps during
the slump), a marvelous smooth texture results.
Of course you need a sandblasting
setup to take advantage of this tip, but some feel that the ease
of removing kiln wash and related problems such as
devitrification is enough to justify the expense.
Or better yet, avoid getting kiln wash
baked onto your glass in the first place.
Check out this page for more on that
topic.
