When you folks heat color your liners, do you bend the lock tab before or after coloring them?
Also, does anyone have a chart that tells you what temperature will give you what color?
I put the bolsters and liners of a folder in my oven and held them at 600 for an hour and they came out the same color they went in. I thought ti started turning bronze at 450?
Oh well, live and learn.
I torched the bolsters and got a nice blue color on them, goes well with the red maple burl scales.
Thanks for any tips or info you can give me and if it's been posted before I'm sorry for beatin a dead horse. The search feature is down for some reason.
Take care folks!

Michael,

Titanium takes a lot higher temp to color than steel. You can get a nice blue by going to 1100 D. F. and holding a short time about thirty minutes. 1050 with a two hour soak will give a beutiful red violet blue hue. I bend the lock before and the heat from coloring stress relieves the liner.

Thank you Bill!!!
I don't know where I came up with that 450 to 600 degree crap, lol.
Since bronze comes in before the blue I bet 950 or 1000 would be about right for it. I'm going to experiment some if I can't find the info online.
 
I think it *starts* bronzing somewhere around 700-800 but I can't be sure since I have always just used torches. I would like to do some pieces in a HT oven or a kiln though just to try getting really consistent tone (and without having to build an anodizer). It's frustrating to get that perfect shade of gold or blue (or worse yet, magenta or green), then a small fluctuation in output of some kind (like crap in the nozzle that suddenly sprays out) causing annoying little speckles!!!
