Look at Simon's text & pictures. He mentions coating, heat treatment and electrolysis as methods of colouring. He also mentions not using abrasives for cleaning, but suitable solvents.
Is he wrong too? - He seems to be confirming much of what I said from the beginning and hasn't said any of the effects shown on his photos are a result of just riding the bikes.
Then look at his pictures. Ask yourself - why would manufacturers go to the trouble of colouring exhausts as they do, if indeed they'd turn those beautiful colours all by themselves through just riding the bikes anyways?
Why would they say use suitable solvent, paper towel and elbow grease rather than an abrasive?
If you read my responses, on page 2 you'll find I did say heat from a Torch would cause blueing. I never denied that as you try to make out? I then pointed out there is another method of blueing titanium. I didn't say it was the only
Colouring of titanium is a chemical reaction to combine the metal with oxygen through the use of strong heat or oxidation through acids and electrolysis. Either method causes a deposit of oxidised titanium on the surface.
By combination with another element, you have a coating of oxidation
. I'd assume basic chemistry and physics was something you learnt at school - Remember any of it?
Fact is, the blueing in Simon's pictures is all factory produced, not
from riding the bikes. Is it really that hard for you to understand?
