They use the titanium oxide in fireworks and what not and i heard that grinding dust of it can be ignited.

The person who told me not to grind it has WAY WAY more experiance then anyone on this forum- the head of titanium industries uk.

James i dont want to imagine your gran grinding her hips away.

Ed, it depends on the titanium,

Alpha type titaniums contain aluminiums, oxygen, nitrogen. wereas beta types contain molybdenum, iron, vanadium, chromium, manganese etc blah blah

titanium has been known to catch fire easily, 360s disc caught fire when we were making it- i through some tango on it though so it was ok lol.. sam smith told me about the large titanium turbine blades in jets which can spontaniously catch fire once.

I believe mark lumb also told me at the euro champs that he didnt want to angle grind little spinners blade off because the dust that comes off can cause cancer. (he made Glyn do it i think lol)
