Falling Particles from the Top

of a Brick Kiln

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

If you have a sandblaster available, it's an excellent tool to use to remove embedded kiln dust particles from a glass piece.  It usually only takes a few passes with the blaster to remove the surface particles.  Obviously, this will frost the piece, so you'll need to re-fire to fire polish the piece and restore the shine.

If you don't have access to a sandblaster, another abrasive technique that sometimes works is to use a diamond hand pad.  This is slower than a sandblaster, but is much more even that a tool like a Dremel, which can dig into the surface and is more resistant to smoothing out during a fire polish firing.

Other grinding and polishing tools (a handheld water fed grinder, for instance) can work as well.  The key to success is to move the grinder around, rather than keep it in one place.  Also, finish with a grit of at least 220 (and preferably 400); the finer grits will lead to better success with fire polishing the piece afterwards.

Click here for the next part of this tip, which deals with ways to prevent kiln brick dust from falling onto your piece in the first place.
