From the Axminster sale, Cocobolo from T/R. Friction finish.

Enjoyed this, unusual colours in the Cocobolo, done for a colleague, hope he likes it.

Great pen there. I be realised cocobolo came in purple.

It's odd, was a lot more brown when it was delivered, the more I got into the blank, the more purple it got. It has finished up nice, just not what I had in my mind at the start. But that's wood for you i guess.

The oil on the new surface of the wood is oxidising which gives it the finished colour and it will change with some cocobolo with time. Nicaraguan cocobolo in particular can be turned white but within a few minutes will start to go orange. If you want to accelerate the process generate a bit of heat by holding the blank and spinning at low speed. I am sure someone from the Health and Safety Police will question this but it gives you an idea of how warm it can get and as you dont want it to get to hot its a heat control. Put it on the window sill before you finish it and watch it change colour. Putting a finish on will slow the change as most are UV inhibitors. With time it will return to the colour of the blank.

Most of the really oily woods change colour to some extent and return to their outward appearance over a period of time. I have an order for a Lignum Vitae pen which is currently sitting on the window shelf and has been turned over a couple of times. I will leave it there for a couple of days to get a really dark green finish. Because it takes longer to oxidise than others finishes really slow the colour change in Lignum very significantly.

That is really handy to know, I did a LV pen a couple of weeks ago which was a lovely green colour as a blank, disappointed me no end when turned as all the colour seemed to disappear. I will leave it on the window sill to see what happens.
