[Rockhounds] H P 10 " Saw -

[Kreigh Tomaszewski]

Charles,

Silica materials produce sparks when cut. I think it is caused by
triboluminescence (light from pressure). You can reduce it by slowing
down your feed; it is always best to let the diamonds do the work, at
their own speed, so your blade lasts longest.
