The first line of defense for treating falling
kiln brick particles involves vacuuming the roof of your kiln.
Although kiln brick particles aren't normally hazardous, it's best
to use a HEPA type vacuum. It's essential to use the vacuum very
carefully, especially around the lid elements. If you're not
careful, it's possible for the vacuum to touch the elements and
cause them to break.
Another thing that often helps is to use a stiff
(but flexible) paint brush on the bricks. The idea is to
dislodge loose particles before they have a chance to fall onto your
piece. Once you've brushed the top surface of the kiln (and
the earlier advice to be careful around the elements applies here
also), it's a good idea to vacuum the kiln thoroughly to clean up
If you've had occasional (or regular) problems
with loose particles, do a maintenance checkup at regular intervals
(monthly or so), and repeat the cleaning and vacuuming process.
This will keep loose particles to a minimum and virtually eliminate
the problem of falling brick particles.

be used to coat the kiln brick so that particles won't fall.
