<p align="left"><font face="arial,helvetica"><font lang="0" face="Arial" size="2" ptsize="10" family="SANSSERIF">Today I had a fresh roll of 0000 steel wool catch fire from grinder sparks. Just 5 seconds of low level flame (like alcohol flames) and another 5 second of glowing strands until it went out. Of course it went out -- steel is not a combustible material!!<br /><br />I was using an angle grinder (hand held, and this wasn't piano work). The sparks were shooting about 3 feet across my bench where the roll of steel wool was. If it had been resting on something like paper towel, that might have been more serious.<br /><br />Watch your sparks!<br /><br />John Baird</font> </font></p>
