Here's a couple:

1) Steel wool. Quite flammable (huge amount of surface area for thin wire).
I've heard of a few fires caused by the stuff catching a grinder spark.


2) Grinding both aluminum and steel on the same
grinding wheel can create thermite. This can cause the wheel to
explode. Lee Valley is a good contact for this - -they had an
article on their website about a specific occurrence.

Wow! This is something very interesting! Thank you very much.

I found the said article in the sharpening section of Lee Valley's
website.


Thank you very much,

Looking forward to your article (where will it appear?).
