Preventing Falling Particles from the Top of a Brick Kiln

This is part four of a multi-part tip on falling kiln brick particles.  Click here to go to part one.

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 loose particles.

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.

Coming next -- products that can be used to coat the kiln brick so that particles won't fall.
